TUCSON, Arizona — Police in Tucson are close to wrapping up a prostitution investigation in which four officers have been implicated.
Police Chief Roberto Villasenor said Monday that investigators were working with the Pima County Attorney's Office on potential charges.
Villasenor wouldn't comment on the four officers suspected of being involved in the illicit massage parlors being investigated.
The officers have not been charged. They are being investigated internally by Tucson police and criminally by the Arizona Department of Public Safety.
Villasenor said police began receiving tips about illegal activity at a massage parlor in 2011. At the time, the department's unit that specializes in sex crimes had been disbanded and the complaint went to the liquor licensing unit.
Police got more tips in 2013 and 2014, and a full investigation began in September 2014.
Villasenor said investigators have connected two massage parlors involved in illegal activity.
Police discovered early this year that four officers may be involved with the parlors.
"Obviously I am rather disgusted by the fact that we have public safety officers who are potentially involved in this," Villasenor said. "It goes against everything we stand for."
