The man, in his 30s, is thought to have been working as a communication officer at the nearby headquarters of Britain's MI6 intelligence agency, the Daily Mail reports. The man hadn't been seen for 10 days and is believed to have been dead for some time. The cause of death has yet to be determined. His cell phone and a collection of SIM cards were found carefully laid out elsewhere in the apartment. Police and counter-terrorism agencies are investigating the killing, but no arrests have been made.
