Simegnew Bekele, the top Ethiopian engineer who was found dead in a car in the capital, Addis Ababa, on Thursday morning, was killed as a result of a bullet wound, the police have said.

A handgun was found in the car.

But at a press conference, Police Commissioner Zeynu Jemal did not say whether police thought the wound was self inflicted or if Mr Simegnew was killed by someone else.

The death of the engineer, who was in charge of Ethiopia's high profile Grand Renaissance Dam project, has shocked many in the country.

As news of his death spread, there was a spontaneous demonstration outside the state broadcaster's offices in Addis Ababa, with people calling for "justice for the engineer”, the BBC's Kalkidan Yibeltel reports.
