Police have been searching the canal in Melling in an effort to find anything linked to local gangs.
Officers were joined by an Underwater Search Team to conduct patrols both in and out of the water in Sefton and parts of Knowsley and Liverpool.
An open land search was conducted in Melling on the Liverpool and Leeds Canal leading into Kirkby, where two burnt out bikes and bolt cutters were recovered.
Under water, divers recovered a number of items including an encrypted device that will now be subject to a full investigation.
Inspector Jonathan Coote said: “It is always good to have the support from specialist teams, including these highly trained divers to ensure that we can thoroughly search the area.”
The day of activity was based around Sefton and Knowsley, with the intention of disrupting criminality and reassuring our community.
Officers conducted three warrants, one at an address on Stanton Crescent, Kirkby where two air rifles and a small amount of cannabis was seized.
Another on Ridingfold, Halewood saw a 51 year old woman arrested on suspicion of production of cannabis, possession with intent to supply Class B drugs and abstracting electricity after officers recovered 28 cannabis plants and a further amount of drying cannabis with a street value in its thousands.
The final warrant was on Sidney Powell Ave, Kirkby where a 26 year old man was arrested for possession with intent to supply Class B drugs. During a search at this address, around £2000 in cash was also seized.
Officers were also based on Liverpool Road, Huyton conducting a road operation where advice and enforcement was given to road users. One car failed to stop but officers caught up with the driver, a 27 year old man who was arrested on suspicion of drug driving and fail to stop.
In addition to this, officers were deployed across Knowsley resulting in intelligence being gathered, stop search powers being utilised to seize drugs and further arrests being made in relation to a variety of offences.
Inspector Jonathan Coote concluded: “It has been a positive day I am pleased that various teams have come together in order to protect our communities.
“Without the assistance of our Underwater Search Team, the encrypted device would not have been located and this will now go towards helping with ongoing investigations to bring offenders to justice.
“These deployments are crucial in finding criminals and getting further information to keep you safe and we will continue to conduct them on a regular basis.
“We develop these operations based on our own investigations but they are hugely benefitted and shaped around the information we receive from the public. Therefore, please keep on reporting crime to us, stay vigilant and help us to look after yourselves and your loved ones.”
