Six released Pakistanis were from the Amritsar Central Jail, two from the Tihar Jail in Delhi and four from Gujarat. Those released from the Amritsar jail had spent four to 17 years in prison. Majority of the prisoners were arrested for entering India without mandatory travel documents including passports and visa, the officials said. Some had stayed in the prisons exceeding their jail terms as the Pakistan High Commission was not issuing them Emergency Travel Certificates, they said.
