SAN FRANCISCO (CBS SF) — A man who threw concrete and bricks at police while on a building’s ledge in San Francisco’s Financial District on Monday afternoon is the same person who stood nude atop a signpost for hours last week, police said Tuesday.

The man was taken to San Francisco General Hospital for psychiatric evaluation early Tuesday morning after the incident began around 3 p.m. Monday, according to police spokesman Officer Gordon Shyy.

Police responded to a report of a shirtless man on the promenade at Four Embarcadero Center on Drumm Street. When the officers made contact with the man, who was wielding a knife, he immediately hopped onto the ledge of the building and threatened to jump, police said.

During a standoff, the man vandalized a large window on the building and also threw concrete chunks and bricks at officers below, according to police.

Police negotiators were eventually able to convince the man to come off the ledge and took him into custody at about 12:15 a.m., Shyy said.

The man, whose name is not immediately being released, is in his mid 20s and is a Bay Area resident.

Shyy said he is the same man that stood atop a “Do not enter” sign on Drumm Street between Clay and Sacramento streets starting around 10 a.m. Friday.

Police shut down the street until the man eventually came down around 2 p.m. During that incident he had also taken off his clothing.

Shyy said he had been taken to San Francisco General Hospital on Friday and was not arrested after he underwent a psychiatric evaluation.

He remained at San Francisco General Hospital for further mental evaluation this afternoon, Shyy said.

Upon his release he faces charges that include assault with a deadly weapon, vandalism, trespassing and brandishing a knife, according to Shyy.
