Gerry Adams, the Sinn Féin leader and chief architect of the Irish republican movement's peace strategy, has been arrested by police over a notorious Troubles murder that has haunted his political career for decades.
Gardens in the Andersonstown district of west Belfast, was charged with aiding and abetting in the murder – a count he denies. Five others have been detained and questioned by detectives, culminating in the arrest of Adams.
