ALTADENA, Calif.—Six people have been injured after two Pasadena police helicopters came into contact over a helipad.

The injured, including the pilots, sustained minor injuries Saturday and were taken to nearby hospitals for further evaluations.

Police Lt. Phlunte (fuh-LAHN-tay) Riddle said one helicopter was landing and another was taking off when the mishap occurred.

FAA spokesman Allen Kenitzer said the two Bell OH-58A helicopters had substantial damage. Television news footage show one helicopter's rotor blade had toppled and its tail broke.

Kenitzer said his agency and the NTSB are investigating the accident.

Riddle said one helicopter crew was on regular patrol while the other was assigned to monitor traffic from the UCLA-Southern California football game at the Rose Bowl.
