Washington, September 16: US police have arrested a laboratory technician thought to be the prime suspect in the murder of a female graduate student at Yale university.
Neighbours hung over their railings and cheered as Raymond Clark, 24, dressed in a tight fitting white shirt, was led, handcuffed, from his apartment building Middletown, Connecticut.
As he was driven away police re-entered the apartment to search it for DNA and other physical evidence that would connect him to the murder of Annie Le, who disappeared on September 8.
New Haven Police Chief James Lewis said police were hoping to compare DNA taken from Mr Clark to more than 150 pieces of evidence collected from the crime scene.
