A major weapons haul recovered during a security alert may help thwart death, injury and misery, police have said.
Around 16 modern semi-automatic handguns and more than 800 rounds of ammunition were seized on the Manse Road area of Castlereagh on Friday evening.
Detective Superintendent Sean Wright, from the PSNI's serious crime branch, described the haul as significant.
"The recovery of these weapons has undoubtedly thwarted the attempts of criminals to inflict death, injury and misery on the community," he said.
"Police are determined to work to protect communities from these threats and I would appeal to anyone who noticed any suspicious activity in the area of Glen Cregagh Road at the junction with Manse Road, known locally as Cregagh Glen, Castlereagh to contact them."
Parts of the Manse Road were closed overnight as detectives investigated the scene in the Lisnabreeny estate.
The weapons and munitions were then taken to a secure location for further forensic examinations.
South Belfast DUP MLA Jimmy Spratt said the discovery was shocking, given the general peaceful nature of the area.
"Lisnabreeny House is owned by the National Trust and is in an area where many people walk on a daily basis, and only a short distance from Lagan College," Mr Spratt said.
"It is a very worrying development that these arms have been found there. I would urge anyone who noticed any suspicious activity or has any information to pass it on to the PSNI immediately. "
