Security has been beefed up at Pattaya Remand Prison after an unidentified number of gunmen opened fire on the facility in the early hours of yesterday morning.
The attack occurred about 1.30am when gunmen sprayed bullets at the prison’s compound in Bang Lamung district, injuring a male inmate and damaging prisoners’ sleeping quarters and the outside wall.
Police found more than 30 spent M16 rifle shells at the scene.
After the incident, two companies of the Corrections Department’s special task force were deployed at the prison over fears of a possible repeat attack.
The shooting happened about a month after a group of gunmen shot at Pattaya prison warder Wutipong Krajuikrajai’s home in Bang Lamung district with M16 rifles on July 19.
No one was injured, but Mr Wutipong has been transferred to Bangkok for his own safety.
Police believed the gun attack on Mr Wutipong’s house stemmed from his crackdown on the smuggling of drugs and mobile phones into the prison.
Local police investigators are working to establish if the two incidents are linked.
