A limousine driver hired to take a group of high school students to the prom has been arrested after the students suspected he had been drinking.

Lowell police say 45-year-old Brian Harrison of Tewksbury, Mass., was charged late Friday with operating a motor vehicle while under the influence.

Police say two female students that Harrison picked up suspected he may have been drunk. One called a parent, who called police.

The students, from Lowell Catholic High School, refused to get into the limo, and the driver left. Police say he returned later, told the students he was sorry and tried to persuade them to get into the vehicle.

Harrison was released on bail and will be arraigned Monday in Lowell District Court.
