Pakistan's anti-graft body has filed a corruption case against deposed prime minister Nawaz Sharif and three others

Lahore: Pakistan's anti-graft body has filed a corruption case against deposed prime minister Nawaz Sharif and three others for their alleged involvement in the illegal allotment of land in Punjab province about 34 years ago.

An arrest warrant has been issued against the 70-year-old three-time premier who is in London for medical treatment.

Former prime minister Nawaz SharifThe National Accountability Bureau (NAB) has approached an anti-corruption court to declare Sharif a proclaimed offender since he did not respond to any of its summons.

The three other accused named in the case filed by the NAB are Jang/Geo media group owner Mir Shakilur Rahman, former Lahore Development Authority (LDA) director Humayun Faiz Rasool and former director (land) Mian Bashir.

In 1986, when he was the Punjab chief minister, Sharif had allegedly allotted 54-'kanal' (canal) land in Lahore to Mir Shakilur Rehman in violation of rules.

Rahman, who was arrested on March 12, is on judicial remand.

Nawaz SharifSharif had left for London in November after the Lahore High Court granted him a four-week permission to go abroad for treatment.

Last month, a fresh picture of ailing' Sharif having tea at a London cafe along with his family went viral on social media, sparking a debate on his health with the ruling Pakistan Tehreek-i-Insaf members demanding his return to face corruption cases.

Sharif was given bail in the Al-Azizia Mills corruption case, in which he was serving a seven-year prison sentence in Kot Lakhpat Jail.

He was also given bail in a money-laundering case to facilitate his travel abroad.

Sharif was diagnosed with "complicated coronary artery/ischemic heart disease with significant disease burden".
