PHILADELPHIA (AP) - The FBI says a flight bound for Dallas has returned to Philadelphia after law enforcement officials received a tip that liquid explosives could be on board.

FBI spokesman Frank Burton says US Airways Flight 1267 was called back to Philadelphia International Airport after officials received the anonymous tip.

Passengers were removed from the plane and bused away as law enforcement vehicles surrounded the aircraft. Video from TV stations showed law enforcement officials removing a person from the flight and police dogs on the tarmac.

Airport spokeswoman Victoria Lupica says there were 98 passengers on board. She says no other flights have been affected by the activity.

Chief Inspector Joe Sullivan says the caller identified the passenger and said he was flying to Texas with a dangerous substance.

He says the passenger actually had nothing dangerous and committed no crime.
