A British oil worker has reportedly been kidnapped in Indonesia.
Engineer Malcolm Primrose, 61, was ambushed by an armed group as he travelled back from a mine site in the Aceh region, reports said.
There were no indications of shots being fired, the BBC reported local police saying.
A spokeswoman for the Foreign Office said: "We are aware of an incident and are in touch with the local authorities."
Mr Primrose is said to work for mining company Medco E&P and was in a car with his driver when confronted by the men.
The drilling supervisor was kidnapped on Tuesday en route from Medco's oil-drilling site in Blang Simpo to his home in Seumali village, the Jakarta Globe reported.
East Aceh police chief Muhajir told the newspaper: "The six perpetrators, carrying three rifles and one pistol, fired a warning shot into the air while intercepting the victim's car."
The men tied up the driver and put Mr Primrose in their car before driving off toward the Ranto Peureulak subdistrict, he said.
He told the paper: "Police officers, with the help of soldiers, are combing the surrounding areas where the victim was kidnapped and the remote areas in Ranto Peureulak to hunt the perpetrators."
