Detectives from ‘Titan’, the north-west’s regional organised crime unit, had gone to the flat after a discovery of
drugs earlier in the day at a tyre fitting centre in Huyton.
Merseyside Police patrols had followed a Ford Fiesta car and its occupant left the vehicle and went into a tyre fitting yard on an industrial unit.
Officers detained three men inside and recovered a quantity of suspected drugs, reports the Liverpool Echo .
Another man was arrested close by and a fifth man was later arrested in the Kirkdale area. Further suspected drugs were found in the Ford Fiesta.
Some of the suspected drugs were also hidden within a tyre that was in the process of being refitted to a wheel rim.
Later enquiries led Titan detectives to the flat in Garston where an estimated 150kg of what is believed to be amphetamines and mephadrone were found.
All five people have been arrested on suspicion of conspiracy to supply Class A and B drugs and are being held at police stations across the North-west. The drugs have been seized by the police for further examinations.
The five people arrested on suspicion of conspiracy to supply Class A and B drugs are A 44-year-old man from Vauxhall, a 36-year-old man from Huyton , a 30-year-old man from Huyton, a 28-year-old man from Huyton and a 22-year-old man from Huyton.
