An IT worker sacked for lying on his CV hacked into his former company's systems and removed vital information, New Scotland Yard has revealed.
Julius Oladiran, 46, of South Norwood, London, lost his database developer job after employers realised he was not qualified and had lied about having a BSc, an MSc, and working for the Ministry of Defence and the Labour Party.

He installed spyware on the company's network to find out what former colleagues were saying about him. His departure meant that a project had to be cancelled, which led to job losses at the small company.
Oladiran was discovered when a company worker noticed his mouse moving around the screen apparently by itself.
The hacker was sentenced to two months in jail on Wednesday in Southwark Crown Court, after pleading guilty to obtaining employment by false representation and computer hacking. He was also ordered to pay the company £3,200 in compensation.
DC Mark Roberts, from the Economic and Specialist Crime Unit at the Metropolitan Police, said, "This man was clearly dishonest and the sentence reflects this.
"He used his knowledge of computers to hack into the system even after he had left the company."
IT security companies have warned businesses to take measures against aggrieved former staff.Graham Cluley, senior technology consultant at security firm Sophos, said, "Every so often there is a story like this - where a member of IT staff feels that they have been unfairly dismissed, but finds it all too easy to break back into the network and cause havoc."
Stuart Hodkinson, general manager of Courion Corporation, added, "Businesses really need to have technology in place that allows them to keep tabs on who has access to IT systems. Until the issue of access assurance is prioritised, we'll continue to see such breaches in organisations."
