New York resident Corey Green had to undergo surgery over the weekend to restore blood flow to his genitals after a police officer in the city’s Brooklyn borough allegedly kicked him between the legs during a criminal investigation. Green, a 33-year-old pest exterminator with two children, had been standing with a group of men police were questioning in connection to the robbery of a takeout food delivery man in Brooklyn’s Bedford-Stuyvesant neighborhood Saturday.

Even though he was not identified by the victim as the culprit, police accosted Green, with one officer allegedly throwing him to the ground and another allegedly stomping on his groin with a boot, crushing his scrotum, his lawyer, Sanford Rubenstein, said. “This is certainly an outrageous example of wrongdoing, and we are calling on the Brooklyn District Attorney’s Office to present evidence to a grand jury,” Rubenstein said, according to a New York Daily News report published Tuesday.

The New York Police Department’s Internal Affairs Bureau was investigating Green’s claims, but it has offered a significantly different version of events. An NYPD spokesman said Green sustained the injury by running from officers into scaffolding.

Green, who police also said had 15 prior arrests, told investigators Monday that cops ordered him and his friends to leave a nearby apartment at gunpoint and stand in a lineup for the delivery man, Rubenstein said. Police took him in on an outstanding warrant for a DWI arrest but later transferred him to a hospital when they determined he had sustained a serious injury, the police spokesman told the Daily News.

“It was inhumane. It was done to inflict a powerful pain,” said Corey’s father, John Green, 52. The case is far from the first time city officers have been accused of disturbing acts of brutality. In 1997, several NYPD officers were found guilty of assault and other offenses for arresting Haitian immigrant Abner Louima and later beating and sodomizing him with a broomstick at a police station in Brooklyn.
