A Massachusetts police officer resigned after leaving his beat to see a dwarf porn star called "Bridget the Midget" and lied about the visit during an investigation into the incident, local media reported Tuesday.

Officer Richard P. Bennett, 28, deserted his late-night patrol to visit a gentleman's club where adult film star Bridget "The Midget" Powers -- billed as "the world's smallest porn star" -- was performing last month.

Bennett was in uniform at the time of his visit to Club Alex's in Stoughton and was reported to authorities by at least five other officers, said Stoughton Police Chief Paul Shastany.

He then reportedly lied about the visit during an internal investigation into the incident, the Patriot Ledger reported.

"Mama told me there would be days like this," Shastany said, on confirming Bennett's resignation. "We are not red-faced. In fact, I am pretty proud [other officers] stepped up."

Bennett, who last month received a commendation for his work in a March murder case, resigned on June 30 rather than face disciplinary action, Shastany said.
