A court here on Monday extended, for seven days, the police custody of Khalistan Liberation Force (KLF) chief Harminder Singh Mintoo, who had escaped from high security Nabha Jail in Punjab.

Additional Sessions Judge Reetesh Singh, extending Mintoo’s police custody till December 12, also allowed police to keep him in handcuff as and when required.

Mintoo was arrested at the Nizamuddin railway station in Delhi on November 28, less than 24 hours after he and five others, escaped from the high-security jail as it was attacked by 10-12 armed men.

After arrest, Mintoo was produced before the court here and sent to police remand for interrogation till December 5.

Delhi Police had earlier informed the court that Mintoo was earlier a member of the banned terror organisation Babbar Khalsa International (BKI), a Khalistani militant group, but later joined the KLF, of which he later became chief.

Police had also told the court that Mintoo had gone to Pakistan and attended a training programme conducted by the ISI.

Delhi Police has recovered a pistol from his possession and also slapped charges under Arms Act.

Mintoo was arrested by Punjab police in 2014 and has 10 cases against him. He was deported from Thailand.
