SAN DIEGO - The owner of a Howard Johnson Hotel in Mission Valley will have to take steps to curb prostitution, according to terms of a settlement announced Thursday by the city of San Diego.

Chhatrala Hospitality Group, LLC will be required to hire a 24-hour security patrol, install additional security cameras, post signs to deter criminal activity, take a cash deposit for all rooms rented with cash, photocopy all guest and visitor identification cards, register all guest and visitor vehicles, and install additional lighting, according to the City Attorney's Office.

The company also will have to maintain a list of people to whom they should not rent rooms and educate and train employees on hotel rules and regulations for guests and visitors.

The City Attorney's Office said police vice officers made 18 prostitution-related arrests in less than one year at the hotel in the 1600 block of Hotel Circle South -- including one that involved a minor who was a victim of human trafficking.

The facility had no security presence, inadequate lighting, limited video surveillance and didn't require a deposit from cash customers.

"Our office will continue to use the Red Light Abatement Act to help clean up neighborhoods impacted by owners who allow their properties to be used to facilitate criminal conduct," City Attorney Jan Goldsmith said.

The hotel also will be fined almost $22,000 to cover the city's investigative costs.

A manager of the hotel said the problems have been addressed and cash guests are now required to put up a $250 deposit, a local TV station reported.
