Older brother of B’klyn teen killed by cops shot ‘innocent’ girl in the arm last summer

Brooklyn teen Kimani Gray, who was fatally shot by cops when he pulled a gun on them, has an older brother who pumped a bullet into a girl over the summer, authorities said.

Omar Gray, 20, shot a 17-year-old girl — an apparent innocent victim — in the arm during an afternoon Brooklyn drive-by Aug. 18, law-enforcement sources said.

Omar Gray was charged with assault and gun possession in the shooting. He pleaded not guilty and was freed on $50,000 bail.

Cops said Kimani, 16, was a gangbanger looking to rob someone the night he was killed. Police have said the officers who shot him fired in self-defense after he pulled a gun on them.

His family denied he had a weapon. They demanded that the Brooklyn DA’s office investigate Kimani’s death.

The Brooklyn DA’s office is now probing the case.

Kenneth Montgomery, the lawyer representing Kimani’s mom, Carol Gray, yesterday said he had “no information about’’ Omar Gray’s bust.

“I don’t see how that affects my representation,’’ he added.
