PORTLAND, Ore. (KOIN) – The former massage therapist who inappropriately touched at least 8 women during their sessions will spend 2 years in jail.

Benjamin Thomas Collura pleaded guilty to 3 counts of 3rd-degree sexual abuse and one count of 2nd-degree sexual abuse.

As part of the plea agreement, Collura will not be able to practice massage therapy until at least 2022. He will also have to register as a sex offender.

The investigation began in February 2016 after police received a tip Collura sexually abused a massage client at a Southwest Portland spa.

The first complaint revealed that a 31-year-old woman told police she had received a massage at the River’s Edge Hotel & Spa when Collura sexually abused her during the massage.

During the investigation, detectives learned Collura had worked at 2 Massage Envy locations between 2010 and 2013, one in John’s Landing in Southwest Portland and one in the Lloyd District in Northeast Portland.

Collura was arrested on March 9, 2016 by detectives assigned to the Portland Police Bureau Sex Crimes Unit.

As part of the agreement with prosecutors, Collura will not be allowed to enter River’s Edge Hotel & Spa or Massage Envy locations.

Multnomah County deputy district attorney Jeff Auxier commended the victims for coming forward in the case.
