EL CAJON, Calif. -- The El Cajon Police Department, which last month started posting on its Web site images of women on "Geo-probation" due to prostitution arrests, has added a batch of johns to the page, a sergeant said Wednesday.

"Geo-probation" means people convicted of certain place-related crimes are banned from those areas. In the case of prostitutes, it usually means cheap motels or streets known for prostitution.

The 16 johns posted on the Web site range from 23 to 58 years old and have been convicted of soliciting prostitutes in the city, said El Cajon Police Sgt. Frank LaHaye.

All are ordered to stay away from areas known for prostitution, such as the 500-1600 blocks of West Main Street and the 100-300 blocks of El Cajon Boulevard, according to the Web site. If spotted in the area, they can be picked up for a probation violation.

The idea is to enlist the populace in running prostitutes and their associates out of town, LaHaye said.

The postings include photographs, descriptions and other relevant information aimed at helping people identify repeat offenders, LaHaye said.

The images can be found at El Cajon Police under the "Geo - Probation" button.
