Family members of Lim Chin Aik, a fisherman who died after allegedly being beaten up by a mob of over 30 people, have urged authorities to expedite their murder investigations under Section 302 of the Penal Code.

Lim, from Kuala Sepetang, Perak, died on Sept 16 at the Hospital Raja Permaisuri in Ipoh - six days after being warded for multiple injuries from the alleged beatings.

Their request was handed over to the police in a memorandum addressed to inspector-general of police Khalid Abu Bakar at Bukit Aman headquarters this morning.
