Police have arrested three men after discovering a cannabis factory where up to 300 plants, with an estimated street value of £300,000, were being grown.

Officers raided the two-storey house in Highfield Road, Isleworth, yesterday (Wednesday, June 4) at about 3pm.

They arrested three men at the property, all of whom are understood to be in their 30s, who have been bailed to return for questioning.

Police believe 2-300 cannabis plants were being cultivated at the house, in four rooms across both floors.

PC Tom Blair, of Hounslow Neighbourhood Policing Team, said he hoped the raid would send out a message that drug cultivation and dealing would not be tolerated in the borough.

"We would encourage people to report any suspicions they have to us on the non-emergency police number 101," he added.
