MELBOURNE, Fla. -

Melbourne police Sgt. Jamie Rocque has been suspended and remains on paid leave while an internal affairs investigation is ongoing.

"Based upon recent incidents, including last night, that have come to my attention, I am immediately placing you on suspension with pay until further notice," a letter to Rocque from Police Chief Steve Mimbs reads.

The letter was written July 3, and it's unclear to what Mimb's statement, "including last night," is referring.  A police spokesman said he could not comment because of an ongoing investigation, Local 6 News partner Florida Today reported.

Five days before the letter was written, four guns were stolen from Rocque's home.

An arrest warrant affidavit, filed by Melbourne police, outlines details of the theft:

Rocque was out of town on June 28, when his live-in girlfriend, a recovering drug addict, called a man to buy $60 of cocaine, the document said. The man met the woman at the community pool at Pinewood Village subdivision near Parkway Drive and Stewart Road in Melbourne, where the woman and Rocque lived.

The woman went to the house to get money to pay her seller, records show, and the man followed. He said he wanted to rob the house, according to records.

The man took jewelry and four handguns, including a Wesson revolver and two semiautomatic handguns, from the officer's house.

Rocque used one of the guns while on duty. At least two of the guns are still listed as stolen in a Florida Department of Law Enforcement database.

Stone and Rocque's girlfriend are not facing drug charges, online court records show.

Rocque has been with the department since 1985 and was promoted to sergeant in 2001. He earns $65,665 per year.
