The Brooklyn dad who ran away while his 18-year-old daughter was being gang-raped at gunpoint walked into two local delis to try to get help — but was too drunk for anyone to understand him, witnesses said Monday.

“He was swaying side to side. He asked me, ‘Lend me your phone.’ I said no,’’ said a worker in one of the shops, Zaida Deli and Grocery.

Four suspects are in custody and still being questioned by cops at Brooklyn’s Special Victims Unit, cops said. They have yet to be charged.

“He didn’t tell me it was an emergency or ‘I need to call the police’ or of course I would’ve given it to him or just called the police for him.”

Two of the five teens accused of attacking the girl in the playground have admitted to being at the scene and even having sex with her — but claim it was consensual, law enforcement sources said.

But “at this juncture, we have no doubt she was raped,” said Police Commissioner Bill Bratton.

Police charged four teens for their roles in the gang-rape early Tuesday.

Denzel Murray, 14, Shaquell Cooper, 15, Ethan Phillip, 15, and Onandi Brown, 17, were each charged with rape, forcible compulsion, criminal sex act and sex abuse, police said.

The four teens were all charged as adults and were being held pending arraignment early Tuesday. A fifth suspect was at large.

Two of the teens were brought in by their mothers Sunday night, the third was picked up at an undisclosed location, and the fourth turned himself in, sources said.

“She has cuts and bruises consistent with being physically attacked,” a source added of the victim.

Police said the girl told detectives in a “detailed interview” at her house that one of her attackers had a bright red “satin-type’’ jacket on.

A video of the teens at a local bodega shows at least one of them wearing such a jacket, police said.

While two of the teens claim they engaged in consensual sex with her, a third suspect said he left the playground before the assault, sources said. The fourth teen is refusing to talk.

“They’re four neighborhood kids,’’ the police source said. “There is one guy outstanding. [But] we got a good lead [on him].”

Police said they have video that shows the girl and her dad buying 22-ounce cans of beer at a bodega and entering the park before the attack at the Osborn Playground in Brownsville around 9 p.m.

The victim told cops that she and her 39-year-old dad — whom she only recently reconnected with after being adopted — were drinking near the handball courts “to be away from the police,” sources said.

Their plan backfired when the teens, including one with a gun, confronted them and ordered the father to scram, the pair told cops.

The dad went to the Zaida Deli, then the Brownsville Plaza Deli.

“I could just tell [he was wasted] by the way he was acting,’’ said a worker at Brownsville Plaza.

Surveillance video from the store shows the victim’s father walking inside before he begins to chat with two men. He does not appear to be frantic or in distress.

After walking out of the store, the dad drunkenly ran past a marked police car before eventually circling back and alerting the cops to his daughter’s attack — 20 minutes after the alleged rape first began to unfold, sources said.

Local activists complained that residents didn’t learn of the attack until it was publicized by the media over the weekend — and Mayor Bill de Blasio joined in the chorus of gripes Monday.

“The mayor was informed on Sunday of the tragic assault in Brooklyn. After further conversations with the NYPD, the mayor now believes strongly that the local community should have been informed sooner and has instructed that the NYPD notify communities more quickly moving forward, whenever appropriate,” a rep said.
