Turner, who police said has no connection to the Broncos or the NFL, was arrested in October by the Arapahoe County Sheriff’s Office for an unrelated incident. While investigating that incident, several women came forward to say that Turner had identified himself to them as a player for the Denver Broncos, Castle Rock police said.

It's not clear if those other women gave Turner money, the Castle Rock spokesman said.

Turner was arrested on Dec. 28 for the alleged scam and faces charges of felony theft, forgery, criminal impersonation and identity theft, police said. He was taken to the Douglas County jail and released on bond.

A Dante Sir Foster never played in the NFL, but there was a Donte Foster who signed with the Minnesota Vikings in 2014. The real Foster re-tweeted a comment about Turner's alleged sham, writing that he was "sad to hear" about it.

A spokesman for the Broncos told NBC News that the team and NFL security were aware of the alleged scam but could not comment further. The Vikings did not immediately return NBC's request for comment.
