Man shot in the head in NYC subway during rush hour; person of interest in custody

A man was shot in the head at a Brooklyn subway station on Thursday afternoon, police said.

Cops and sources said the shooting took place at around 4:50 p.m. on a train or in the platform of the A/C Hoyt–Schermerhorn Streets station — which houses the NYPD’s 30th transit precinct.

A person of interest was taken into custody, the NYPD said.

The victim was brought to Brooklyn Methodist Hospital in critical condition, according to sources.

It wasn’t immediately clear what sparked the violence.

Officials said northbound A/C trains would experience delays as police investigate.
