Inspector-general of police Khalid Abu Bakar said the suspect who was arrested for a shooting rampage at the Lim Chong Eu Expressway in Penang last night had a military background.

Khalid said the 35-year old bodyguard, who was detained with another suspect, was also "mentally ill".

The other suspect, a 32-year old man, was in the same car as the Datuk who was reportedly shot by the bodyguard.
