A man who was allegedly making a fuss on BART as it traveled through San Francisco has been detained this morning, after his disturbing behavior delayed trains and sent police to the scene.

According to Twitter user We Built This City, BART travel was halted at the Balboa Park station at around 6:25 this morning.

Several minutes later, BART tweeted a response, saying that police were called regarding an "unstable patron" at the Balboa Park Station — perhaps the man WBTC refers to in the below tweets.

KRON 4 reports that the patron in question was "yelling and banging on BART doors." Eventually, they report, BART police officers were able to detain the man, and travel resumed thereafter.
