A school bus driver who is charged with sexually assaulting a student on a school bus told the student not to say anything or “I’ll go to jail,” police said Tuesday. Alan Demand, 51, of Fowler Street in New Haven, assaulted the student “numerous times” and carried on an illegal sexual relationship until the student reported the assaults to a school resource officer, they said. The student was between the ages of 13 and 15 at the time, Sgt. David Tammaro said. Demand was charged with two counts of second-degree sexual assault, one count of illegal sexual contact and one count of second-degree unlawful restraint. He was in custody on $50,000 bail Tuesday morning, police said, and was scheduled to appear in Superior Court in Milford for an arraignment later in the day. According to police, Demand assaulted the student between October and December. He also talked to the student several times on a cell phone and at one point texted a picture — which police described as “sexual” — along with instructions: “Please don’t tell your mom anything else cause I’ll go to Jail.” Police didn’t say whether the student is a boy or a girl. Detectives from the department’s Special Victims Unit made the arrest, police said. Demand worked for Winkle Bus Company. Hugh Keefe, who represents the company, said it suspended Demand as soon as it learned of the allegations. He has not been fired; he must be presumed innocent until proven guilty, Keefe said. The bus company has “an excellent safety record and never had a driver charged with anything like this in the past,” Keefe said. Demand has no recent arrests or convictions on his record, according to judicial branch records. According to his online resume, he also has driven school buses in Bridgeport and North Haven and has been a shuttle driver in New Haven. He has driven elderly passengers as well as students, the resume says. He has been known to maintain order during trips “in order to ensure safety measures,” it says. It also says he has “Exceptional Interpersonal Skills.” reported by AP and CT news
