An angry crowd protesting police treatment of minorities gathered Monday outside of the Bronx residence where an unarmed teen was fatally shot by cops last week.



Ramarley Graham, 18, was killed by narcotics detectives who followed him as he fled into his parents' Williamsbridge apartment. He was in the bathroom when he was shot once in the upper portion of his chest.



About 500 demonstrators attended the rally and called for an end to police brutality.



"We are human beings. Stop treating us like animals," Frank Graham, the slain teen's father, told the crowd. "My son did nothing wrong. I want justice for my son, my baby."



Juanita Young, 57, the mother of Malcolm Ferguson, a 23-year-old who was killed during a struggle with a narcotics officer in 2000, joined in the rally to show solidarity with Graham's parents.



"My heart went out to the mother here. It brought back so many bad memories," said Young, whose wrongful death suit led a Bronx jury to award her $10.5 million.



"They keep killing innocent young men. It just hurts to see the abuse of power. There are no words to describe our pain as mothers."



After gathering outside of the E. 229th St. apartment building where the Grahams live, the boisterous crowd marched to the local 47th Precinct stationhouse while chanting: "NYPD, KKK, how many kids did you kill today?"



They ratcheted up the rhetoric with placards that read: "Judgement Day for NYPD child killer," and also called for the resignation of Police Commissioner Raymond Kelly.



Police posted ten officers to guard the stationhouse door as the crowd filled up the block.



Graham's sister, Leona Verga, spoke into a megaphone and remembered her brother as a "well-respected" young man. She pleaded with other young black men to stop using he "n-word" and letting their pants sag.



"If you all continue with these shenanigans against each other, we all are going to be targets and there is going to be no one left," she said.



The cops involved in Graham's death have been taken off the streets and given administrative duties while prosecutors investigate the shooting, according to a spokesman for the Bronx District Attorney.
