A former British soldier arrested over the 1972 Bloody Sunday killings has been released on bail, pending further inquiries.
The unnnamed former paratrooper was held by the Legacy Investigations Branch, which is investigating the deaths of civilians as a result of the Londonderry shootings.
Thirteen demonstrators were killed, while a fourteenth died later.
The Police Service of Northern Ireland said the 66-year-old was initially arrested on suspicion of murdering three civil rights demonstrators in Londonderry on Bloody Sunday.
He is the first to have been arrested as part of the investigation
Richard Kemp, a former commander of British forces in Afghanistan who was a colonel in the Royal Anglian Regiment whose servicemen were involved on the day of the Bloody Sunday shootings said it was “disgraceful” that the troops faced arrest and potential prosecution.
According to the Sunday Times (£), Mr Kemp said:
A source close to the police who has seen government files on the investigation surrounding the Bloody Sunday shootings told the Sunday Times (£) that interviews under police caution were "expected imminently". The spokesman added:
Up to 20 retired British soldiers face arrest for murder over murder, attempted murder of criminal injury over the Bloody Sunday shootings, according to the Sunday Times (£).
The move comes three years after the £200m, 12-year inquiry by Lord Saville into the shootings produced its report.
Saville found that all those shot by paratroopers during a Catholic civil rights march in the nationalist Bogside area of Londonderry in January 1972 were unarmed, and that the killings were both “unjustified and unjustifiable”.
The judge concluded the army had lost control of the situation, that the soldiers had fired first and some of them had then lied to cover up their culpability.
Up to 20 retired British soldiers face being arrested and questioned by police for murder, attempted murder or criminal injury over the Bloody Sunday shootings more than 40 years ago, according to the Sunday Times (£).
The Ministry of Defence has started hiring lawyers who will represent the soldiers, most in their sixties and seventies, when they are questioned under criminal caution about their roles in the shootings.
Some of the soldiers who opened fire on marchers, killing 14, may face prosecution and a trial that will reopen wounds from one of the most notorious incidents in the history of the Troubles.
Retired British Army colonel Edward 'Ted' Loden, a commanding officer during Bloody Sunday, has been killed in a suspected attempted robbery in Kenya, the Times reports.
The 73-year-old was visiting his son in Nairobi, when the family were ambushed by armed thieves who forced their way into the compound. No one else was injured in the attack.
A solicitor for one of the families said the offer of £50,000 compensation to the families of those killed by British paratroopers during a civil rights march in Derry, in 1972, said the offer was derisory and an insult to those killed.
Kate Nash, whose brother William was killed and father Alex injured, said:
The families of 13 people killed by soldiers in Northern Ireland on Bloody Sunday have been offered £50,000 each in compensation.
Paratroopers opened fire on unarmed civil rights marchers in Derry in 1972.
Thirteen others seriously injured have also been offered £50,000 each as part of a total compensation package from the Ministry of Defence (MoD) worth around £1.3 million.
DUP MP Gregory Campbell said the dedication of 30 senior officers to another investigation into Bloody Sunday could run up a bill close to £8 million. He said the murder investigation showed a clear "hierarchy of victims."
Tory MP Patrick Mercer said he did not think the murder inquiry into Bloody Sunday was necessary, and that he "struggled to see what it would achieve."
Mr Mercer, who served in the Army during the so-called Troubles in Northern Ireland, said he did not think a murder probe would deliver justice for the victims, as the majority of the troops who were involved in the atrocity are untraceable, extremely old, or dead.
