Police are searching for a suspect who allegedly shoved a man in front of a train at the 170th Street station in the Bronx Wednesday morning.

The incident occurred around 7 a.m., police said according to PIX11. The victim’s condition is unknown at this time.

Service on the B was initially interrupted during the morning commute as police investigated, but has since resumed with delays. Southbound B trains are currently running express from Tremont Avenue to 167th Street, the MTA said.

Additionally, “extensive delays” are also expected on the D line, according to the New York City Subway Twitter account.
