Burglars stole a computer from a house in Briar Hill, Northampton, after throwing a brick through the kitchen window.
The property, in Thornhill, was broken into sometime between 10am and 5pm on Monday, May 18.
The laptop that was stolen was a relatively new, black Acer computer which was vitally important to the owner, police say, because it was “used to help overcome a medical condition”.
Witnesses, or anyone who knows anything about this incident, can call Northamptonshire Police on 101.
