Detectives believe three house burglaries in the same night in Ilkeston are all linked.
The homes, in Portland Road, Milfield Road and Manners Road, were burgled overnight between October 26 and 27.
The offender forced open a window at the Portland Road property and stole a silver Macbook laptop, cash and a black and fluorescent green mountain bike from inside.
A window was forced at the house in Manners Road, where car keys, a phone, a tablet and a purse were taken.
An Acer laptop and a red and black laptop bag were stolen from the Milfield Road address.
All three burglaries are being linked and detectives want to hear from anyone who might have been offered any similar sounding items for sale.
