A man has been accused of attacking and raping a woman who broke off a relationship with him.
Morris Holton III has been charged with aggravated sexual assault.
Houston police said Holton forced his way into the woman's apartment on Tuesday.
Holton put a knife to the woman's throat and tied her wrists and ankles with zip ties, investigators said.
Detectives said Holton blindfolded the woman and used a Taser gun to burn her all over her body.
Holton let another man into the apartment and forced the woman to perform oral sex, police said.
Holton is being held in the Harris County Jail without bond.
