Warrenpoint police deaths inquest: Insufficient evidence for crash verdict
The jury in the inquest into the death of four Police Service of Northern Ireland officers has concluded there was insufficient evidence to firmly establish the cause of the crash.
The constables died when their armoured vehicle crashed and caught fire in County Down in November 2008.
The jury said the crash was most likely to have been caused by road condition, a manhole cover and excess weight.
The officers were travelling on a road near Warrenpoint to help a colleague.
Assistant Chief Constable Alan Todd said the officers who were killed, Constables Kevin Gorman, Declan Greene, Kenny Irvine and James Magee, "represented everything I admire and respect and everything that's good about policing".
He added: "Over the course of the investigation into this incident, we identified and implemented a series of actions across the service, recognising that we have a responsibility to do the very best that we can to keep our people safe, as they carry out what is often difficult and sometimes dangerous work.
"We have added additional vehicles to our training fleet; have upgraded escape routes from armoured vehicles, re-issued directions on the use of the armoured fleet and ensured officers are given the appropriate training on the use of emergency escape hatches.
"We will now take some time to review the substantial information presented over the last two weeks, to identify and implement any further actions to keep our officers and the public safe."
