India, Jan. 2 -- Agra Police have made one arrest in connection with the murder of a teacher at an AMU school in Aligarh last month, they said.

The man arrested, Salman Qureshi, is said to be a close aide of the three key accused and brothers Zubair, Fahad and Yasir, who allegedly helped them flee after the murder. The brothers were still at large when this report was filed.
