Bangladesh police arrested Riazul Islam as he was walking home from his in-laws' house. At 3:15 a.m., he was shot dead in a sandy field beside a set of railroad tracks north of Dhaka.

Police say he was killed in a gunfight with other drug dealers, and they recovered 20 kg of marijuana from the site. His parents say the officers extorted money from them and then killed him.

"I knew my son was in police custody. All of a sudden my son was dead. I couldn't believe it. The police took money and they still killed him," said his mother, Rina Begum.
