STAMFORD — A city man was charged Monday with the assault of his girlfriend in front of their young son earlier this year.

Richard Ramos, 26, of Summer Street, was charged with violating a judge’s protective order, two counts of third-degree assault, risk of injury to a child, threatening, interfering with an emergency call, unlawful restraint and disorderly conduct.

Sgt. Brian Butler said the arrest stems from a complaint made in late January when Ramos’ girlfriend came to police headquarters to complaint about an assault that occurred to her in December.

After an argument began, the woman reportedly woke their two-year-old son up and was walking out of the home with him when Ramos allegedly pushed her up against a wall, injuring her back, Butler said.

After getting into his car to drive her home, Ramos allegeldy got angry agitated again, calling the woman names and when she threatened to call 911 he punched her in the chest, causing her to drop her phone while their son was in the back seat, police said.

He picked it up and threw it out the window. The woman got out of the car and was unable to find her phone. When she got back in she said Ramos violently pulled the vehicle forward, almost striking her with the car, Butler said.

Ramos was held in lieu of a $50,000 court appearance bond and is being arraigned on the charges Tuesday.
