Police identified a 19-year-old man on Thursday as the gunman who shot a 1-year-old boy two weeks ago while trying to gun down a rival in Brooklyn.

Lyemel Summerville wounded the baby when he opened fire on a street in Brownsville on Aug. 19, police alleged.

He was aiming for a 20-year-old man and struck him in the leg with one bullet that passed through and grazed the baby, police said.

The wounded man was taken to Brookdale Hospital, while the baby was treated at Kings County Medical Center. Neither was seriously injured.

Police were searching for Summerville Thursday night and said he was about 5-foot-10 and 165 pounds.
