Police said GPS software helped locate a registered sex offender after officers believe he punched a 17-year-old girl several times in the face at a west side bus stop.
According to a Madison Police Department report, Ricky Warren, 21, of Madison, was arrested on suspicion of physical abuse of a child and disorderly conduct. Tammy L. Cox, 24, and Pamela L. Chamblis, 31, both of Madison, were cited on suspicion of battery, the report said.
Police said the 17-year-old victim had a past relationship with Warren, the teen told police she encountered him after getting off a bus Tuesday afternoon. She was with a 19-year-old friend. Police said surveillance video showed Warren, Cox and Chamblis attacking the teenagers. Police said Cox and Chamblis were assaulting the 19-year-old, knocking her to the ground, repeatedly punching and kicking her, while Warren punched the 17-year-old.
Police said the two teens were taken to the hospital by Madison Fire Department paramedics.
Investigating officers contacted the Wisconsin Department of Corrections after learning Warren was wearing a GPS monitoring bracelet. DOC staff members kept the MPD apprised of Warren’s movements and police said he was taken into custody after showing up at a DOC probation and parole office on Odana Road.
The female suspects were located at a residence on Atticus Way; one denied being at the West Transfer Point, even after being confronted with surveillance video evidence, the report noted.
Police said Warren's criminal history includes convictions for sexual assault and burglary.
