A Morristown woman was arrested after police say she sprayed a pregnant woman with mace and repeatedly hit her with a softball bat.

Jacqueline Rivera, 24, of Fredericks Street, was arrested and charged with aggravated assault, possession of a weapon with purpose to use it unlawfully against another person and unlawful possession of a weapon at 7 p.m. Tuesday night.

Officer Jermaine Marbley responded to a report of three to four women assaulting one woman with a baseball bat, according to the police report. When Marbley arrived, Morristown EMS staff was already treating the woman, who was bleeding profusely from her head, according to the report.

A witness at the scene told the officer the victim had received a phone call from an unknown woman, who stated she was coming over to beat her up, according to the report.

Another witness then said a group of women arrived and one of them, later identified as Rivera, sprayed mace into the victim's eyes and proceeded to assault her with the softball bat, the report said. Several people on the scene yelled at Rivera to stop assaulting the victim as she was several months pregnant, according to the report.

Rivera then dropped the bat and fled south on Speedwell Avenue with several others, according to the report.

Later, while being treated at Morristown Medical Center, the victim repeated what witnesses had told police earlier, noting she had seen Rivera and the others around town but did not know their names, according to the report.

Rivera was arrested and charged later that evening. She was transported to the Morris County Correctional Facility on $5,000 bail, which was posted on Wednesday.
