Four people have been charged with drugs offences following a police operation targeting suspected dealers.

Police seized substances believed to be heroin after arresting five men and two women in Blackburn town centre and at a house in Great Harwood at around 9pm on Saturday.

Two woman and a man have been released without charge on police bail, pending further inquiries.
