Police are investigating a break-in at a business in North Street, Bourne, on Tuesday when power tools worth more than £1,000 were taken.
Last Monday there were two burglaries in the Deepings.
Jewellery worth £4,000 was stolen from a home in Thackers Way, Market Deeping and an electric tile cutter was taken from a property in Ascendale, Deeping St James.
