Bryan Adams' guitar 'defaced' in Cairo airport

Despite being aworld-famous rock star, Bryan Adamsisn't immune to frustrating run-ins with customs officials, with the Canadian singer claimingEgyptian authorities leftgraffiti marker scrawls on a vintage guitar and other instruments.

Earlier this week, Adams travelled to Cairo to play several concerts by the Giza Pyramids.

On Thursday evening, he posted animageof his vintage Martin acoustic guitar with graffiti on it -- the result of a run-in with a border official at the Cairo airport -- on his Instagram and Facebook accounts.

"Airport customs graffiti on my 1957 Martin D-18 from Egypt. Back to the luthier," Adams wrote.

A number and an illegible word in Arabic are seen scribbled in green ink on the mahogany instrument.

According toAdams, theproblems began upon arrival.

"We almost didn't get the equipment into the country, and when we did it was all marked like this,"he told AgenceFrance-Presseon Friday.

"There were absolutely no apologies."

An unnamedcustoms official contacted by AFP saidinstruments are marked with serial numbers, although usually with stickers.

Customs director denies claims

However, Jamal Turki, director of customs at Cairo International Airport, rejected Adams' claims.

"I followed the big fuss the international artist made on Facebook and these accusations are false," Turki told NBC News.

"We don't write on equipment whether arriving or departing and the international artist should specify which department wrote on his guitar."

Turkisuggested that someone else wrote onAdams' instruments sometime between the airport and the singer reaching hishotel.

"It may have been his room number or the car number taking him to airport," Turki said. "The number doesn't mean anything to us in the airport."

Despite the situation, however, Adams thanked hisEgyptian fanswho reached out to him andassured them of his continued love for the country and its people. He alsosaid the guitars can be fixed.

This latest incident follows a similaronelast July, when Adams posted via Twitter thatone of his guitars had been tagged with black markerby Air Canada staffers.

Adams is currently on a world tour promoting his latest album, Get Up.
