On August 27, a METRO Transit Authority customer service operator received a phone call during which the caller said he had left a cup on the light rail vehicle that might explode, blowing up the train. According to court documents, METRO police found that the call came from a phone number belonging to Alan Tadeo Baker.
Surveillance video also reportedly showed a man who matched Baker's description board the train, place his cup in a seat and then exit again, leaving the cup behind. Officials say the surveillance video also showed the man attempting to get back on the train, but the doors had closed and the train was pulling away from the station.
Police say further investigation matched up Baker's use of his Q-card, video and audio surveillance and the recorded threatening phone call.
Baker, 45, is charged with terroristic threat, a felony charge. Bond has not been set in the case.
