One person was killed and five others injured in a drive-by shooting in Brooklyn on Wednesday night, police sources said.

Several gunmen inside a BMW sedan opened fire into a crowd gathered on Hawthorne Street near Nostrand Avenue in Prospect Lefferts Gardens at about 10:25 p.m., sources said.

A man, 23, was fatally struck in the hail of bullets, sources said. Four other men and a woman were also hit, according to sources.

“The lady who was singing. She got hit in the stomach,” a witness told The Post. “A lot of people got their leg shot,” added the witness, who wished to remain anonymous.

Another witness said they heard close to two dozen shots.

In another shooting, a 28-year-old man was gunned down outside an apartment complex on Herkimer Street near Hunterfly Place about 9:35 p.m., cops said.

The unidentified victim, who was struck several times, was taken to Kings County Hospital, where he was declared dead, authorities said.

No arrests were made in either shooting as of early Thursday, authorities said.
