Four young girls, ages 8 to 16, were seriously injured in a meat cleaver attack by a relative in a Brooklyn home Sunday morning.

An 11-year-old girl locked herself in a room and called 911, prompting police to respond.

Officers shot the suspect, 49-year-old Lun Chang Chen, after he refused to drop the weapon and advanced toward them.

All four girls were hospitalized and are expected to survive.

A fifth child escaped to get help, the New York Post has reported.

The suspect is in critical condition, and the motive remains under investigation.
