Osceola County Sheriff's Office detectives July 27 added four charges to those that registered sex offender Alexander Colon, 32, of 205 London Drive, Kissimmee, already faces.

In mid-June, deputies arrested Colon and charged him with one count of accessing a computer without authority and with failure to register as a sex offender. The new charges are four counts of sexual battery.

The victim, a former girlfriend, told deputies that on four separate occasions Colon had sex with her without her consent. She told detectives the incidents occurred at Colon's residence. The first time it happened was in September of 2009; the most recent was in May.
