A fifth teenager is in custody in connection with last week's alleged gang rape in Brooklyn.

Four other teens are already facing charges in the case, which includes rape and sexual abuse.

Police say 17-year-old Onandi Brown, 15-year-old Ethan Phillip, 15-year-old Shaquell Cooper, and 14-year-old Denzel Murray were caught on surveillance video near the Brownsville park where cops say the attack occurred.

They are all being charged as adults.

Invesitgators say an 18-year-old woman was raped inside Osborn Park Thursday night.

They say her attackers threatened her father with a gun, and made him leave the park.

"Eleven o'clock this morning we arrested a Travis Beckford," said NYPD Chief of Detectives Robert Boyce. "He's a 17-year old male. He is the fifth person that we arrested in this case, and we believe he's the final person.

"He was apprehended by members of the warrant squad in Brooklyn. We're speaking to him now, so he's the fifth and we believe this is the end of — no one else we're looking for."

The investigation is ongoing.
