The fiend who allegedly fatally beat a mom in front of her 7-year-old daughter and then left the frightened tot with the body whined in Manhattan court Sunday that he needed to be put in protective custody.

Tiliek Shamel Thompson, 41, beat to death 27-year-old Lovay Williams with her child in the home, then carted off evidence in blue shopping bags and cut his hair to try to dodge detection, prosecutors and the victim’s kin said.

“Give him the gas chamber!” the dead woman’s father, Nuquan Williams, screamed at Judge Linda Capitti during Thompson’s arraignment.

Thompson was ordered held without bail on charges including murder and strangulation for the grisly Sept. 6 slaying inside Lovay Williams’ Washington Heights apartment.

He turned himself in to cops Saturday after receiving numerous threats, according to his lawyer, Neville “Nod” Mitchell — who asked the judge to provide the accused killer with protective measures while in jail.

“I would ask for protective services,’’ Mitchell said, adding that his client told him he “has a psych diagnosis.”

Williams’ fuming aunt Missy Wright later said outside court, “How dare you ask for protected custody.

“How dare you ask the courts to protect you.”

Another cousin, Lexus Singleton, said, “ It’s just very frustrating.

“His lawyer tried to make him like he was an angel, and it was a slap in the face to the family. But one thing I will say, we will get justice, and we have strong evidence on this case. So he will not get away with this.”

Thompson was granted protection in jail.

Manhattan Assistant District Attorney Michael Perez said surveillance video captured Thompson entering the apartment Sept. 5 and leaving the next day after making two trips to retrieve items from the apartment, carting them off in “distinct” blue shopping bags.

 Mitchell suggested at one point that someone else could have come and gone from the crime scene by a window.

“What the f–k?” a family member said.

After allegedly killing Williams, Thompson went on the run.

Thompson was charged after turning himself in at the 33rd Precinct stationhouse on Saturday.

“The heat was on and either way he was gonna get caught,” Williams’ dad told The Post earlier Sunday. “He had no choice but to turn himself in. The streets were looking for him.

Law enforcement was looking for him, and he knew he had to do the right thing by turning himself in to face what he did, because he knew he was wrong.”

 Singleton said Thompson cut his hair after the incident to throw cops off his trail.

 Mitchell urged people Sunday to withhold judgment.

“I’m just asking people to let the process play out,” he said. “And whatever my client is charged with and found guilty or not guilty of it, you know, we’re here to adjudicate that specifically with respect to my client.”

Williams’ sister, Asia Walker, said the family had known Thompson for some time.

“It’s confusing to me because we knew this man for too long,” she said.

“I don’t even know what caused this. I can’t remember her saying they even argued before.”

Lovay’s mom, Moinica Manners, said Sunday that her granddaughter is “holding up the best that a 7-year-old that witnessed such a heinous crime could.”

Thompson is due back in court Friday.
