Update, 12:07 p.m.:

An incident in which a 70-year-old man was struck by a train in Central Tampa may have been a suicide attempt, Tampa Police said Tuesday morning.

The train was headed west near Busch Boulevard and Florida Avenue when the man was spotted on the tracks, according to Tampa Police Lieutenant Ron McMullen. The man appeared to drop something on the tracks and attempted to pick it up when he was struck, McMullen said.

"It takes miles for these trains to stop," McMullen said. "The train saw him, gave several warnings and attempted to stop. The train horn and the attempt to stop was what attracted other people's attention. Whether or not this was a suicide attempt is something that the investigation will determine."

The victim, whose name has not been released, is in critical condition at St. Joseph's Hospital, McMullen said.

Traffic at Busch Boulevard and Florida Avenue will continue to be affected for several hours as the police conduct their investigation, officials said. The southbound portion of Florida Avenue from Busch to Yukon Street has been closed.
