An 84-year-old man died shortly after noon Friday when he leapt from the Casco Bay Bridge onto the rocks at the end of Thomas Knight Park in South Portland.

South Portland police said they got a call around 12:30 p.m. from someone who saw the man climb over a security fence on the northbound span of the bridge. The caller said the man was standing on the outer ledge of the bridge, near the pedestrian walkway on the South Portland side of the bridge.

Police said they arrived just as the man jumped off. Police, fire and rescue workers reached the man, but said he was dead when they arrived.

The man was a South Portland resident, police said. They declined to release his name.

South Portland Police Chief Edward Googins said no foul play is suspected in the death.
