A San Antonio man faces felony charges after police say he assaulted his girlfriend twice, threatened to kill her with a knife, and then sent threatening texts demanding she drop the charges, according to arrest affidavits.

Johnathan Gamez, 31, is charged with continuous violence against the family and obstruction or retaliation, both felonies.

San Antonio police were called Oct. 2 to an assault in progress in the 2400 block of East Houston Street, the first affidavit says.
