An 18-year-old man arrested in the violent sexual assault on a woman at a Tacoma day care is expected to be charged Thursday in Pierce County Superior Court.

Andrake Morris was arrested Tuesday for investigation of rape and robbery. Police said they believed he could be responsible for other assaults in Tacoma as well.

Police believe he attacked the worker at the Tender Heart Learning Center early Monday when she arrived for work. She let him inside because he said he wanted to enroll a child. The attacker ran off when another worker arrived.

The victim spoke to KIRO-TV, her face still swollen from the beating. She says the man made her feel uneasy, then he suddenly knocked her to the floor, assaulted her and beat her with a chair.
