A Philadelphia police officer was arrested yesterday on assault charges stemming from alleged altercations with his live-in girlfriend and his ex-wife in April.

Police said Officer Howard Lomax, 40, allegedly assaulted his girlfriend inside their home on April 20. Lomax is also accused of assaulting his ex-wife at her home on April 24.

Officials said the women suffered minor injuries but were not hospitalized.

The Police Department's Internal Affairs Bureau and the District Attorney's Office investigated the incidents, and Lomax is also facing two counts of recklessly endangering another person.

Police Commissioner Charles Ramsey has suspended Lomax for 30 days with the intent to dismiss, police said.

Lomax is a 17-year veteran of the Police Department and worked out of the Center City station on Chestnut Street near 7th, police said.

He is the 27th police officer to be arrested in the past two years.
