READING — A prosecutor says a police officer lied about the reason behind a traffic stop, then broke the motorist's cellphone and punched her in the face after pulling her over without sufficient cause.

Berks County District Attorney John Adams announced charges, including official oppression and evidence tampering, against 27-year-old Reading Officer Jesus Santiago-DeJesus.

The officer was arraigned Thursday. Defense lawyer Allan Sodomsky says his client didn't do anything wrong and that a video clip released by prosecutors doesn't tell the whole story. Sodomsky says the motorist refused commands and assaulted Santiago-DeJesus.

Adams says the officer claimed in a report that the woman didn't use a turn signal before the stop, although surveillance video shows she did.

Adams says the officer knocked the phone out of the woman's hand to destroy the video she was recording and wrongly charged her and a passenger.
