An 18-year-old was left in critical condition after he was shot in the head while working at a Flatbush deli Saturday.

Police say the teen was working as a cashier inside the deli owned by his father when gunshots rang out at 1854 Nostrand Ave around 6 p.m.

Surveillance video shows people running out of the deli when the shooting happened.

The teen’s family, who was with him at the hospital on Sunday, say he is in critical but stable condition.

Police say two people are wanted in connection to the shooting.

The shooting is still under investigation.
