NORTHGLENN, Colo. -- A 19-year-old man arrested this week -- accused of sexually assaulting two mentally disabled women he had met online -- may have preyed on other victims, police said.

Nicholas Anthony Meier, 19, was arrested on Wednesday on two charges of sexual assault of an at-risk adult.

The Northglenn man recently contacted an 18-year-old woman in Lakewood and a 21-year-old female in unincorporated Jefferson County, online, Lakewood police said. Both women are developmentally disabled.

Police said after numerous online and texting conversations with them, he met them in person and sexually assaulted each at different times and locations.

Detectives are asking anyone who may have additional information about the cases or about Meier to contact the Lakewood Police Department at 303-987-7111 or the Jefferson County Sheriff’s Office at 303-271-5612.
