GMP said its officers first raided Dearden’s home address – a large plot of land with several containers, buildings and outbuildings on Dyehouse Lane, in Rochdale – in July last year.
Dearden was originally arrested, charged and remanded for a drugs offence but officers received intelligence he had guns at home.
A full search ended up lasting four weeks due to the scale of the property and uncovered five firearms with ammunition and drugs including 10kg of amphetamines valued at £100,000, 99g of cannabis oil valued at £12,884, £57,000 worth of cannabis and £4,685 worth of cocaine.
Dearden also ran a pet shop with his father selling exotic birds.
During the search officers found several hundred different animals including dogs, peacocks, parrots, mink, ferrets, ducks, Koi Carp and a bull.
At one count there were more than 800 parrots in separate outbuildings which had to be removed by an expert.
They were left in the care of Dearden’s father afterwards.
