A senior British executive working with oil giant Exxon Mobil, has been murdered in Belgian capital Brussels.

Nicholas Mockford, the head of marketing for interim technologies at ExxonMobil Chemicals, Europe, was reportedly shot three times whilst walking with his wife to their car after eating dinner at an Italian restaurant.

A witness of nearby the crime scene told Flemish TV what he saw.

"I heard two noises… I don't quite remember. Something like' tak tak'. It sounded odd and I went outside to see what was going on. A woman was lying on the footpath across the street. She cried 'Help, Help'. Another person was lying on the street, next to the car."

He added that he saw the bullet wounds on Mockford's body when paramedics opened his shirt.

"I saw that when paramedics cut his cloths open, he was shot in the chest and in the shoulder. I haven't seen more. Actually he was bleeding from his head too. I didn't see more because I didn't dare to move him."

It was believed initially that Mockford's death resulted from an attempted car hijacking, though their Lexus sports car was untouched after the incident. Belgian authorities have declined to say whether they are investigating the case as a contract killing
