Dozens of homes were evacuated in Birmingham after a bird-scaring device sparked a bomb alert.
Police were called to Brandwood Park Road, in Kings Heath, on Sunday afternoon.
A number of residents had called police to say they had heard a series of small bangs in the back yard of an empty block of maisonettes.
Officers found gas cylinders with wires attached to them.
Homes evacuated
As a precautionary measure nearby homes were evacuated.
Army bomb disposal experts were called in and the device was identified as a bird-scaring device.
Police say they are making inquiries as to who set up the machine, which makes periodic explosive noises to scare birds, in an empty property.
A West Midlands Police spokesman thanked residents for the patience they showed during the alert.
