Pakistan police arrested Imran Khan's nephew and a number of his supporters on Monday for their alleged involvement in the attacks on the security personnel outside a court here over the weekend where the ousted premier arrived from Lahore to appear in the much-awaited hearing in a corruption case.

The raft of arrests was the latest amid the mounting cases filed against Khan, the chief of the main opposition party, Pakistan Tehreek-e-Insaf. Monday's arrests bring the total number of Khan's followers detained in Islamabad to 198 since Saturday. Among those arrested also include Hassan Niazi, Khan's nephew.
