Confidential work contracts, police conduct records and government correspondence are among the sensitive documents abandoned at the former MedServ offices on Manoel Island.

Amid used condoms, syringes and empty spray cans littering the haunting hallways of the abandoned complex are dozens of files marked “confidential” and “for internal use only”.

Times of Malta visited the largely abandoned complex of 17th-century buildings on the small islet, a popular stomping ground for Gżira youths.

The young people who call the area their own regularly break into the complex, sneaking through a number of holes in the mesh fences cordoning off the site.

This is news to me. We should have cleared this out when we left 10 years ago

They use the site to fool around, explore the subterranean bomb shelters or leave graffiti calling cards on the crumbling limestone buildings.

The abandoned files belong to MedServ, a Maltese oil and gas consultancy firm involved in exploration operations since the early 1970s. The offices were vacated in 2001, when the site was taken over by MIDI, a development consortium, as part of the Tigné Point development.

When Times of Malta went on site accompanied by a local who frequents the area, it was clear that the youths were not the only visitors. In fact, during the two-hour tour, one could come across two fashion photo shoots, a group of people setting up a BBQ and another group of locals exploring the buildings.

MedServ executive director Anthony Duncan said yesterday he was surprised to hear of the abandoned documents, which included the dates of birth, identity and passport numbers, photographs and addresses of dozens of former employees.

“This is news to me and we should have cleared all of this out when we left over 10 years ago,” he said.

Mr Duncan said he would be informing the company of the matter and looking into why documents belonging to it had been left behind.
