Police are hunting a gang who allegedly burst into a Perthshire home and seriously assaulted two men.
The attack happened at about 2300 BST on Sunday in Glover Street, Perth.
Tayside Police said three men, wearing blue overalls and black ski masks, broke into the house. They all spoke with Irish accents.
The men are thought to be aged from 20 to 40 and about 5ft 11in. One was of a slim build, the second of medium build and the third was described as fat.
