The PSNI has confirmed that the team investigating events on Bloody Sunday in Derry 44 years ago has forwarded a report to the Public Prosecution Service for its consideration.
Fourteen civilians died as the result of wounds received when British soldiers opened fire on civil rights demonstrators in the city's Bogside area.
The murder investigation was launched in 2012. It was initiated after a UK government-commissioned inquiry, undertaken by Lord Saville, found none of the victims was posing a threat to soldiers when they were shot.
Following the publication of the Saville report in 2010, then prime minister David Cameron apologised for the British Army's actions, branding them "unjustified and unjustifiable".
When the first ex-soldier was arrested, a petition calling for soldiers involved in Bloody Sunday to be granted immunity from prosecution gained tens of thousands of supporters in the UK.
The other soldiers involved won a challenge at the High Court in London that prevented detectives taking them to Northern Ireland for questioning.
Detective Chief Inspector Ian Harrison, from the PSNI's Legacy Investigation Branch, said: "We can confirm a report has now been submitted to the PPS for consideration.
"The families have been informed of this development."
