The arrested person has been identified as Mohammed Fahad Khan (22), a resident of Okhla area of Delhi.
Police said Fahad was carrying a reward declared on him by Aligarh police. He had escaped during police chase two days ago while his younger brother Yashir was arrested after a firing incident in Bara Hindu Rao area. Fahad had also allegedly committed several highway robberies.
"We got information yesterday that he would be coming towards Yamuna Vihar area. Acting on the tip-off, police laid a trap and arrested him from there. He has confessed to his involvement in several robbery cases," said a senior police official.
