A Los Angeles International Airport flight bound for London was cancelled Sunday when a passenger's phone picked up the Wi-Fi signal "al-Quida Free Terror Nettwork" (sic) that was emanating from a fellow flier's hotspot minutes before the United Airlines flight was set to liftoff.

After a concerned passenger notified a flight attendant of the network at about 9:30pm, the plane taxied to a remote section of the Los Angeles airport and was held there for three hours. The plane was searched as passengers of Flight 136 were ordered to power off electronic devices, local media said.

"After an hour, (the captain) said there was a security threat and that we didn't have clearance to take off," passenger Elliot Del Pra told ABC7.com. The person responsible for the hotspot was not discovered, LaWeekly said.

"After further investigation, it was determined that no crime was committed and no further action will be taken,"LAX said in a statement. American Airlines said the flight was cancelled "out of an abundance of caution."

It was the second time in as many months that an Internet indiscretion caused an airline scare. An American Airlines flight from Dallas to San Diego was cut short in August following a tweet that there was a bomb on a plane carrying a Sony executive.
