BOSTON (AP) — A Boston police sergeant has apologized to a 61-year-old man he confronted for videotaping officers as they detained a teenager — an incident that prompted a police investigation into apparent intimidation by the sergeant.

Sgt. Henry Staines met with Lawrence Dugan on Friday and apologized. City Police Commissioner William Evans apologized for Staines’ actions on Thursday.

The video shows Staines telling Dugan he didn’t have permission to film the officers. Staines later presses a fake gun against the camera, saying: “See that, see that, that’s why we’re here.”

A police spokesman says all officers have been reminded citizens can legally videotape them. Staines remains on duty while an internal affairs investigation is underway.
