Three men have been arrested by armed officers following a raid at an address in Derbyshire.
Police searched a house on Jubilee Road, Shelton Lock, at about 1350 GMT on Friday as part of a firearms operation.
Once inside the property officers used a Taser gun on a man who was then arrested on suspicion of affray.
Another man was also arrested on suspicion of affray, linked to a stabbing in Allenton last month.
The third man was arrested on suspicion of possessing class B drugs.
A full search of the house is under way and all three men remain in police custody.
