Police have seized a "substantial" haul of heroin in a raid on a house in Leicester.
Officers executed a search warrant at a house in Pendlebury Drive, Knighton, on Sunday night, following a tip-off from a member of the public.
Three people were arrested on the night. They included a 53-year-old woman who has since been released and will face no further action.
Two men, aged 33 and 36, have been released on police bail as officers continue their investigation.
A substance removed from the house was analysed in a laboratory and was yesterday confirmed to be heroin. It is now being tested further to assess its purity and value.
Inspector Richard Toone, commander of Welford Road police station, said: "It is still being tested so all we can say at the moment is it is a substantial amount of heroin. We cannot put a value to it yet.
"This was the result of information received from a member of the public. Our message to people is to share information like this with us and we will investigate and, where appropriate, take action."
