The 36-year-old took his eight-year-old son hostage after the fight over the device at Taman Seri Kionsom here last Monday.
Police, who were alerted about the 5pm incident, took two hours calming him down after he had shouted at them to back off while the boy was in his chokehold, before he finally let go of the weapon.
City Police Chief ACP Habibi Majinji said besides repeatedly pointing the weapon at the boy, the suspect also hit the son’s head with the screwdriver’s handle several times.
He shouted at the men in blue not to come close to him, threatening to jab the boy with the weapon.
“The suspect would not budge and was not letting his son go despite the boy obviously looking terrified at the time,” he told reporters at the city police headquarters in Karamunsing here today.
“Policemen had to resort to psychology to calm the suspect down before he eventually surrendered the screwdriver to them and was later arrested.”
Habibi said a urine test later found the man positive for syabu.
He added the suspect also had three criminal convictions including for slashing his wife some two months ago.
“The suspect is being investigated under the Penal Code as well as the Dangerous Drugs Act,” he said.
