PROVO — An ex-boyfriend is in jail after police said he broke into his former girlfriend's house and attacked her.

Late Wednesday night, a Provo woman called police to report that she was being attacked, according to an affidavit of probable cause filed in 4th District Court.

She said she had opened the door to find her ex-boyfriend, 26. He forced his way inside and ignored her pleas to leave, according to the affidavit.

He began scratching her so she tried to hit him and push him out but was unsuccessful, so she called 911.

The man picked up bottles, a fan and glasses and threw them at the walls, damaging the apartment and scaring the woman, according to the affidavit.

He then slapped the phone away from the woman's hands and told her not to talk with police.

The woman told police he has been threatening her for weeks and has almost caused her to lose her job, according to the affidavit. He even left a message on her phone right before he came to her apartment saying that if she didn't answer, he would come to her work and things would get "messy," according to the affidavit.

He was booked into the Utah County Jail for investigation of burglary of a dwelling, interruption of a communication device, assault and criminal mischief on $9,999 cash-only bail.
