DOVER, Del.- Dover Police Cpl. Thomas Webster, who was embroiled in a controversy surrounding a charge of felony assault, has resigned. Webster was found not guilty of that charge in December.

The charge resulted from an arrest that occurred in August 2013 while the then-Cpl. Webster was on duty.

Dover Mayor Robin Christiansen said at a press conference that after the verdict, the city and Webster entered into discussions about his future employment with the City of Dover.

He said the resignation was voluntary and submitted on Tuesday.

In May, authorities said Webster, who was assigned to the patrol division, responded to the Hess gas station (renamed Speedway Service Station) for a fight where one person possibly had a gun.

Investigators noted that Webster contacted a man, later identified as Lateef Dickerson, who matched the description of one of the people involved in the fight. Webster attempted to take Dickerson into custody.

Police said then that Webster, along with another officer, held Dickerson at gunpoint, ordered him to get on the ground, and then Webster kicked him in the head once, knocking him unconscious.

After that happened, police said Dickerson was put in handcuffs and taken into custody.

The incident was captured on video by a Dover Police Department in-car camera system.

Dickerson was taken to the hospital for injuries. He was found to have a broken jaw, according to police.
