Man arrested in sexual assault of mother out with baby

Police say they have arrested a suspect after a gunman forced an Arizona mother to take her 2-month-old baby from a stroller and walk to a pathway where he sexually assaulted the woman.

Tucson police did not immediately release the suspect's name on Friday.

The attack occurred on Wednesday as the woman walked home after buying groceries in a pedestrian area of south Tucson with a housing development and big box store. The walking path where she was taken was more secluded.

Police said the victim and unharmed baby were taken to a hospital.

Detectives searched the area for hours and sought help from the public. The department released a composite sketch of the attacker on Thursday.
