Rattu was ambushed, carjacked and shot dead near the Taj Mahal Casino in Atlantic City Sunday.
Rattu, of Old Bridge, was just finishing nursing school. His girlfriend, 24-year-old Radha Ghetia of Sayreville, was also shot and wounded.
Prosecutors said the three suspects in Sunday’s attack stalked people at two other Atlantic City casinos before committing the crime.
20-year-old Phillip Byrd is now in custody, the Press of Atlantic City reported. Byrd was picked up at his home in Camden.
Tuesday, police said they were hunting for Byrd, 20-year-old Eric Darden and 18-year-old Raheem Simmons, who are also from Camden. The trio were allegedly caught on casino surveillance video.
“We arrested [Byrd] last night,” Atlantic County Prosecutor Ted Housel told the Press.
“The individuals who perpetrated this offense we know to have essentially stalked two other areas, parking areas, in Atlantic City,” Housel said.
Police said it was a casino dealer from Bally’s that spotted the suspects acting suspiciously hours before the shooting. He jotted down the license plate number of the group’s stolen getaway car – a 2003 grey Saturn Ion. The car has also been recovered, the Press reported. It had been stolen from Haddonfield last month.
Police said Byrd, Darden and Simmons stalked several potential victims before zeroing in on Rattu.
Investigators believe the trio approached Rattu and Ghetia as they were getting into Ghetia’s Range Rover. They allegedly robbed Rattu and Ghetia, forced them to drive to an alley and shot them, police said.
Police continue to hunt for the remaining two suspects, who have now been charged with murder, robbery and carjacking.
