A man has been shot dead by police in Bedford after he barricaded himself inside a property overnight.

Officers were called to reports of vehicles being damaged at about 10.40pm on Monday and found a man in his 40s who had blockaded himself inside a home and was making threats, Bedfordshire police said.

Armed officers attended the scene along with police negotiators and other emergency services, the force added, and nearby residents were evacuated from their homes.
