Seberang Perai Tengah (SPT) police have denied assaulting S Naidu Agin Raj, who died at the Bukit Mertajam hospital on Saturday.

The 26-year-old lorry driver, who lived with his mother and two younger sisters in Kampung Mainroad, Prai, is the seventh case of custodial death related to Penang police lock-ups or prisons.
