DHAKA, Bangladesh (AP) — An Islamist prisoner who had been freed by gunmen was killed hours later in a gunfight between his accomplices and Bangladesh security officials, a police official said Monday.

Rakibul Hasan and two other convicted militants escaped on Sunday when dozens of gunmen exploded bombs and opened fire on the van transporting them. One policeman was killed in the attack in Mymensingh district, 112 kilometers (70 miles) north of the capital, Dhaka.

Police recaptured Hasan later Sunday. But police official Golam Mostafa said the escaped militant’s accomplices opened fire on police early Monday and Hasan died in the crossfire in neighboring Tangail district.

Local media often describe such deaths in crossfire as an extrajudicial killing, an allegation authorities deny.

Authorities are offering a financial bounty if anybody helps with information to recapture the two escaped prisoners who remain at large.

Hasan had been convicted of murdering a man and sentenced to death.

He and the two other prisoners belonged to the banned Jumatul Mujahedeen Bangladesh. The government says that the Islamist group was broken up after its top six leaders were hanged in 2007 but that it is trying to regain strength.

Jumatul Mujahedeen Bangladesh wants to establish strict Islamic laws in Muslim-majority Bangladesh and reportedly has connections with international radical groups.
