MEMPHIS, Tenn. — A man accused of raping a woman in her apartment is now in police custody.

Donald Gwin was already on probation for another sex crime when this latest attack happened Thursday morning.

Police say Gwin was wearing a GPS tracker at the time a woman was attacked at the Country Squire Apartments.

The woman said her attacker locked her inside her apartment, then raped and choked her at knife-point.

She told police the suspect forced her to brush her teeth afterwards to get rid of the evidence.

Police say the man took the woman’s purse, phone and debit cards.

WREG-TV learned Gwin pleaded guilty in May to sexual battery charges related to a 2012 incident, when another woman said he raped her at knife-point.

Gwin was given a two-year suspended sentence, put on probation for two years and added to the sex offender registry in that case.

Right now, Gwin is being held in jail on a half million dollars bail and is charged with two counts of aggravated rape, one count of aggravated burglary and one count of aggravated robbery.

Residents at the Cordova apartment complex say they’re relieved Gwin has been arrested, but say he never should have been on the streets in the first place.

“If he can do that it shows what kind of heart he has and he shouldn’t be out on the street,” said one resident at Country Squire Apartments.
