A car was broken into in a gated driveway in Barton Seagrave early today (Wednesday).
A man was seen acting suspiciously in Hogarth Drive, between 3am and 3.10am.
Following a search of the area a police dog recovered a number of envelopes.
They contained a quantity of monies that are believed to be sports subs, along with a Morrisons card.
The suspect was described as wearing what may have been a black and blue lightweight jacket and light grey jogging bottoms.
