A CANNABIS factory has been discovered in a village house after a resident complained of strange smells.

Police estimate that the factory in Hilltop, Redbourn, has been running for over three months.

It was only discovered after a neighbour rang the fire brigade to say there was a strange chemical smell coming from the first floor.

After investigating, firemen called police who found a cannabis factory containing a large number of plants at varying stages of growth in the house.

It is understood that police chased a woman before stopping her in Cumberland Drive.

A 41-year-old woman from London was arrested on suspicion of cultivating cannabis and was bailed to Monday of this week. But she failed to answer her bail.

Police think the factory, set-up in a rented house, had been in operation since the middle of last October

A police spokesperson said the property had been searched and items had been seized before it was handed back to the owners around two days later.
