A Black Bronx cell phone technician who cops say was was the victim of a nasty hate crime at the hands of a white off-duty Long Island police detective told the Daily News in an exclusive interview that he fears for his safety in the wake of the attack. Derick Anhwere was working in in Manorville when he was attacked by Rockville Centre Det. John Murphy about 7 p.m. Nov. 3, prosecutors say. “I feared for my life,” Anhwere, 48, said of the clash in an interview at his home in Co-op City. “He was unhinged.” “It’s a clear hate crime,” he added. “I never met him in my life. It’s clear by what he said, the language he used, there was no other reason but hate.” The Suffolk County Police Department’s Hate Crimes Unit arrested Murphy, 40, just before 6 a.m. Wednesday. He is charged with two counts of criminal mischief as a hate crime and aggravated harassment. Murphy, who lives in Manorville, demanded to know what the victim was doing in the area, according to prosecutors. “Get out of here! We don’t want you or your like in the neighborhood, n***er,” Murphy allegedly shouted, according to the criminal complaint against him. “I was working an AT&T cellphone tower,” Anhwere a technician for 12 years, said. “I was testing it. I was verifying the network’s service.” “Our vehicle has amber lights and it shows we are out here doing a service for the community,” he added. “It should show anyone in a position of authority that we are out here doing a service for the community.” Rockville Centre Det. John Murphy leaves First District Court in Central Islip Wednesday. (Newsday / James Carbone) Anhwere is the son of a diplomat who came to United States from Ghana when Anhwere was 6 years old. He was shocked by the clash with the cop. “He said ‘We don’t want you here in our neighborhood. Don’t ever come back here, N-word’,” Anhwere, . “He was cussing me out. He was abusing me. He was saying all kinds of nasty things to me.” Murphy refused to look at the victim’s credentials, then allegedly kicked his 2023 GMC Terrain, ripped an amber safety light off the top of the vehicle and threw it at him, the criminal complaint says. The light hit the driver’s side door and broke into pieces, which hit the victim’s left cheek, according to court papers. “He said, ‘Where are you from?’ And I said, ‘I’m from right here in New York’,” Anhwere recounted. “And he said, ‘No, you’re not’ and I tried to show him my driver’s license and he said, ‘Shut up you’re lying.’” That’s when things got physical, according to Anhwere. “He reached into my vehicle and opened my door,” he said. “I said, ‘Sir, what are you doing? Why are you entering my vehicle? you have no right to do this.’ ‘He grabbed my computer and I pulled it back.” “He tore the amber light off the top of my roof,” Anhwere added. “I was like, ‘What?’ He said, ‘You better get the f**k out of here.” Anhwere believes Murphy was intoxicated and says he smelled alcohol on the attacker’s breath. “He threw the siren at me and it hit the metal frame of the door and it shattered. A piece of it hit me in the face, my cheek, then he started kicking my car. He put a dent in the door. He was screaming, ‘Get out of my neighborhood!’” “I didn’t know if he was going to pull a gun and I got scared and pulled off,” he added. Anhwere then called 911. “Now I can’t even function,” Anhwere said. “I’m scared when people walk up. He definitely changed the fabric of my work.” Murphy was arraigned Wednesday in criminal court in Central Islip and ordered to stay away from the victim by Judge Bernard Cheng. He is due back in court Dec. 3.  The Rockville Centre police department did not immediately respond to questions about Murphy’s duty status in the wake of the arrest. “He should be held accountable,” Anhwere said. “I don’t want this to ever happen to anyone else. We are out here providing a service.” Cheng ordered Murphy released on his own recognizance after prosecutors asked for supervised release, a higher level of monitoring. Murphy’s lawyer, Anthony DiFiore, did not immediately return a request for comment. “The victim here was just trying to do his job, when the defendant allegedly harassed him and damaged his vehicle,” said Suffolk County District Attorney Ray Tierney. “To make matters worse, the defendant is a sworn law enforcement officer, responsible for protecting the rights of citizens, rather than violating them, as is alleged here.” With Graham Rayman
