Two people have been arrested in Malaysia in connection with the murder of an Irish man.

The body of 50-year-old Brian Patrick O'Reilly was found at his apartment in Penang on Monday evening.

Mr O'Reilly is said to have been employed by a Singapore-based marketing company.

It's believed a cryptic note was left near the victim's body.

Local media reports that a 37-year-old woman and a 43-year-old man have been arrested in connection with the case.

However, police are still searching for a man who's believed to be the main suspect.

Penang police chief T Narenasagaran told the South China Morning Post newspaper: “We have evidence to show the suspect we are looking for has left the country".

They have informed international police, and are continuing their investigation.
