The closure order was issued after officers searched the address in New Bedford Road this morning.
During the search, which was aided by a search dog, police found suspected class A and class B drugs as well as weapons.
A 21-year-old man was arrested on suspicion of possession with intent to supply class A drugs. Two people were also removed from the property and safeguarded, before being directed towards the appropriate agencies.
In a separate incident, community officers visited a house in Villa Road yesterday afternoon to issue a closure order after residents reported concerns about drug-taking. The address was previously issued with a partial closure order but due to the order not working effectively, a three-month full closure order was issued by Luton Magistrates’ Court yesterday afternoon.
