Two people have been arrested following the murder of an Irishman in Malaysia.

Brian Patrick O'Reilly's body was discovered on Monday in George Town, on the northern island of Penang, where he had been working as an IT manager for about a month, official news agency Bernama reported, citing police.

The 50-year-old appeared to have been stabbed and beaten. His body was discovered by a property agent who was visiting his apartment.

A man in his 40s and a woman in her 30s have been arrested as part of investigations.

Three people were reportedly seen entering the apartment with Mr O'Reilly late Friday, and then left shortly afterwards.

"A check of the man's home found a safe in one of the rooms had been ransacked and there were signs of a struggle," a local police official told reporters.

Last night, the Department of Foreign Affairs said it was aware of the case and ready to provide assistance.

A spokesperson said Mr O'Reilly also holds South African citizenship.
