tonight on "nightline" -- extreme pranksters. from an urgent s.o.s. >> we've had an explosion on board. >> to a 911 call that brings out the s.w.a.t. team. >> i shot my wife. >> the people who hack your xbox and tell police they're you. we tell you what's behind the new wave of costly and dangerous high-profile hoaxes. and toxic spray tans? we go undercover to expose why the tan everyone thinks is safer than the sun may be more dangerous than you realize. what you need to know before

taking a glow. plus, ewe pick quaty from a rhinoplasty, a surgeon at night making house calls at the zoo. good evening, i'm cynthia mcfadden. tonight, they're the so-called pranksters, creating havoc with their dangerous and expensive phony 911 calls. and a new technology is making it easier for them to get away with it. from using untraceable internet numbers to hacking an xbox to send a s.w.a.t. team to an incident victim's front lawn. just yesterday, one such fake cry for help sent the coast guard scrambling for hours.

here's abc's linsey davis. >> reporter: for nearly six chaotic hours yesterday afternoon, these helicopters swirled above the atlantic as part of a massive search and rescue operation, the u.s. coast guard looking for survivors of a yacht named "blind date" carrying 21 people. it was allegedly sinking after an explosion off the sandy hook, about 70 miles off the central post of new jersey. this distress call to the coast guard was utterly convincing. >> we have three deceased, nine injured. we've had an explosion on board, that's why we're taking on water. >> reporter: the search went on for hours, but oddly without any signs of an explosion, no debris, no survivors, no witnesses. >> about 6:30, we started looking at the possibility of a hoax call. >> reporter: around 7:00 p.m., the owner of "blind date" confirmed his boat was not in

new jersey and not exploded. the coast guard had confirmed this was the biggest hoax in years. >> you're talking about human life, the coast guard in particular will scramble to go look for people in distress. >> reporter: these prank criminal calls are now so common, there's a term for them, s.w.a.t.'ing. the idea is that pranksters get s.w.a.t. teams sent to your door. the latest estimate for this yacht hoax so far, more than $300,000. the fbi says each s.w.a.t.'ing incident costing an average of $10,000 in resources. beyond the money is the paralyzing fear that the victims experience and the danger they're put in. >> i've got two people held hostages all right? >> right. >> you know what happens to people held hostage? >> reporter: with rifles drawn, a s.w.a.t. team swarms down where inside a teen age girl and

her father were bound and held hostage by a man threatening to kill them, or so they thought. >> i am armed. i do have a pistol and i swear to god i will kill these people. >> reporter: but it turns out no such hostage situation existed. it was a regular night at home for 15-year-old hunter galinas. they come into my room and a gun pointed at me. >> reporter: he had been the victim of a s.w.a.t.'ing prank. s.w.a.t.ing that is so prevalent because the internet makes it easier to make a call without leaving a trace. some calls use the hearing impaired or disabled to contact services. others use a spoofcard. >> we were eating dinner and police showed up with a gun pointed in my face and my mom's face. >> reporter: for lisa, the

s.w.a.t.ers who targeted their family got the information from an x box. >> they surrounded our house. i had no clue what was going on. it was terrible. >> reporter: the police had received these terrifying message, please help, my dad had killed my 4-year-old sister. please help. he killed my mom with an ak-47. >> it makes me very upset and mad at the person. >> reporter: when local authorities failed to find a perpetrator, lisa did her own sleuthing and believed she found out who hacked her x box and sent the original 911 call to police. tyler said he was playing an online game which may have been the reason they were targeted. no one has been arrested.

>> gotta get my son! >> reporter: s.w.a.t.'ing may be new but hoaxes are not. one of the most elaborate hoaxes of all time, the now infamous balloon boy which cost a local colorado town almost$50,000. the world watched and waited as a little boy floated away in his homemade balloon. but it turns out his parents did it all as a publicity stunt for a reality tv show. >> they put on a very good show for us and we bought it. >> reporter: they ended up serving jail time and paid close to $40,000 in restitution. so why do people pull these sometimes extremely dangerous pranks? >> some of the motivation for s.w.a.t.'ing is for the victims or ego. >> reporter: tonight, law enforcement is still searching for the latest yachting incident. if caught, the person will be in a boat load of trouble. they'll have to pay back the

coast guard for their search, not to mention $250,000 in fines and potentially spend up to ten years in prison. proving committing a federal crime like this one is no joke. for "nightline," i'm linsey davis, in new jersey. >> outrageous behavior. thanks to ly thanks. up next, a surgeon by day and why one surgeon is treating man and beast.
