A former Brisbane Freemason has apologised after allegedly being found naked inside a damaged historic pipe organ, surrounded by the remnants of a cheeseburger, in the the city’s Masonic Memorial Centre.

Glenn Langford allegedly broke into the heritage-listed building and flooded it on Wednesday night and was found alongside the burger, a remote-controlled police car and a toy gun.

He told 7 News he was sorry for any damage he had caused - to the pipe organ and the reputation of the Freemasons.

The Freemasons have since told 7 News that Mr Langford is no longer a member.

“Things just got a little bit loose - I can’t explain it at the moment,” Mr Langford said.

“I apologise to all the righteous Freemasons everywhere. I did have a lot of cheeseburgers to give to the homeless.

“I was out of it. I’m going to see a shrink and I won’t drink. But I might try to give out some more cheeseburgers to the homeless.”

Mr Langford said he hoped the organ - reportedly worth millions of dollars and insured - would emerge unscathed from the ordeal.

But he’s unable to return within 100 metres of the centre as a condition of his bail and a caretaker told 7 News they believed the damage could not be repaired.

“Hopefully it’s not that damaged and I am sincerely sorry,” he told 7 News.

According to 7 News, Mr Langford’s lawyer told court he had downed a bottle of Johnny Walker and had been drinking heavily after losing his job and the break-up of his relationship.
