This follows investigations on four police officers who failed to follow procedures while transporting a suspect, who escaped but was rearrested later.
Selangor police chief Datuk Abdul Samah Mat said investigations into the incident revealed there were elements of negligence.
“One area that needs attention is their attitude and their understanding of basic SOP,” he said.
“We are working towards minimising this weakness and we will ensure our officers undergo strict training to avoid such mistakes.”
Samah said while the four police officers — an inspector, a corporal and two lance corporals — are being investigated for negligence, the detainee would also face the consequences for escaping.
The incident took place on December 8, when the officers brought the 34-year-old suspect out in a van to lead them to his accomplice’s house in Paras Jaya, Sungai Buloh.
Three policemen had gone to locate the accomplice, while he was left in a police van with the remaining officer.
The three policemen were later told that the detainee, who was in handcuffs and lockup attire, had broken free after a struggle and fled into a jungle nearby.
Police managed to rearrest the suspect, who is believed to be responsible for 29 criminal cases around the Klang Valley, at an abandoned squatter house in Kampung Seri Gombak, Batu Caves, after a four-day manhunt.
Two of his accomplices was also arrested some 30km away on the same day.
