Anna Lo MLA said: “The people responsible are offering nothing to our society except death, injury and disruption. The vast majority of the population are opposed to their actions.
“Anybody could have been seriously injured or killed had they picked up this device.
“I would like to offer my thanks to the Police and Army officers who dealt with this device and placed their lives at risk to protect the public.
“I would urge anybody with any information about this device to contact the Police.”
