Barnes is also wanted in relation to an earlier sexual assault on a family member and repeated attempts Saturday to lure an 11-year-old girl into his car, Detective Superintendent Marlon Bodden said Monday.
He warned that Barnes has a “violent disposition” and should be considered dangerous, adding that he is known to have access to firearms.
Police released a photograph of Barnes and are urging members of the public not to approach the suspect, but instead to immediately contact police.
The rape occurred Saturday morning, 29 October, after a man in a red Honda Civic hatchback car pulled up at the side of the Shamrock Road, where a 49-year-old woman was waiting for a bus. He offered her a ride and when she refused, he got out of the car, holding something in his hand that was covered by a piece of cloth, and ordered her to get into the car.
He drove the victim to a secluded area in the Admirals Landing area where he raped her, police said.
Police do not know if the suspect was carrying a weapon.
The vehicle was later recovered by police in Prospect.
Shortly after police were alerted to the rape, they received a call saying that a man in a red Honda Civic had tried to lure a young girl into his car three times that morning, as she was waiting for a lift at the side of the road at Victory Drive in Prospect.
“Sensibly, the young girl refused. Subsequently, a family member saw the young girl speaking to this individual in the red car and approached the young girl and the driver drove away,” Detective Superintendent Bodden said.
Around 8.15pm that night, police received another call – this time from a family member of the suspect saying that he “had reportedly sexually assaulted a family member” on an earlier occasion.
Detective Superintendent Bodden said Barnes was known to police, who had already issued an arrest warrant for him last week in connection with an assault occasioning actual bodily harm.
Police have searched premises in Whitman Seymour Drive in George Town and Mahogany Drive in Prospect, where he has lived, but have so far found no sign of Barnes.
“We know that Jeffrey Barnes is aware that we want to speak to him,” said Detective Superintendent Bodden.
Anyone with information is asked to call George Town CID on 949-4222 or Crime Stoppers 800-8477 (TIPS).
