A call to police from St. Vincent’s Medical Center in Bridgeport over the weekend led to the arrest of a 47-year-old Congress Street woman, who police allege broke her 80-year-old mother’s back.

Amanda Jane Yelen was arrested on a warrant Wednesday, charged with third-degree assault on a victim over 60 years old and violation of a protective order. She was held on a $100,000 bond and was scheduled to appear Thursday at state Superior Court in Bridgeport.

Police received a call from hospital officials Saturday that they had a an elderly assault victim there. At first, the report states, the victim, who had a fractured vertebrae, was reluctant to tell them what happened.

According to the mother, the two were arguing last Friday because she wanted Yelen to take her into the pool, but Yelen kept putting her off. She then slapped Yelen, she said, and Yelen then pushed her to the ground.

On Saturday, the mother’s other daughter called, but the victim said she couldn’t get out of bed, and later was seen “hobbling” to the main house on the Congress Street property, where the other daughter and her family live. With her back pain worsening, the mother was taken to the hospital.

Amanda Yelen called police Monday, expressing remorse and said she and her mother were arguing over a phone call when her mother slapped her and she pushed her away as a reflex.

When Yelen turned herself in Wednesday, police said she was belligerent with officers and, at one point, tried to walk out of police headquarters.

Both Yelen and her mother were charged with disorderly conduct after a prior incident at the home June 3 when they were pushing and shoving each other.
