Dubai: A Bahraini appeals court on Sunday reduced a seven-year jail term handed down to a policeman accused of killing a protester in 2011 to six months, a judicial source said.
In a separate case, the court acquitted two other police officers who had faced charges of killing another protester, the same source said.
The first officer was sentenced in January to seven years for beating a protester to death, and the two other officers were acquitted of shooting dead a demonstrator in November 2011.
A number of police officers are being investigated or are on trial for allegedly torturing detainees after hundreds of opposition protesters were rounded up when security forces quelled the protests in March that year.
The authorities say they are implementing the recommendations of an independent commission of inquiry appointed by the king that confirmed allegations of excessive use of force by security forces during the unrest.
Bahrain has continued to witness sporadic opposition-led demonstrations, now mostly outside the capital, since the unrest that started in February 2011.
The International Federation for Human Rights says around 80 people have been killed in Bahrain since the violence first broke out.
