Officers are appealing for information after two bikes were stolen at an address on Northwich Road in Weaverham.
Between 10pm on Friday 27 January and 9:15am on Saturday 28 January thieves broke into a shed in the garden and stole one Nukeproof Mega 275AM bike and one Orange Crush bike.
The offenders then made off in an unknown direction.
