Six people, including two teenage boys, were arrested and a homemade shotgun with ammunition seized during separate anti-crime exercises in Central and North Central Trinidad.
The arrests and seizure took place between Wednesday night and Thursday morning.
During Operation Resolute Shield, conducted between 4 pm and 8 pm on Thursday, officers carried out exercises in the Enterprise, Longdenville, Chaguanas, Charlieville and Caroni police districts.
Based on intelligence received, officers proceeded to a bushy area along Caroni North Bank Road, Caroni.
About 100 metres into the bushes, officers found an unoccupied makeshift wooden structure.
A search of the structure led to the discovery of a black plastic bag containing a homemade shotgun and a quantity of assorted ammunition.
The operation was coordinated by ACP Remy, Snr Supt Bhagwandeen, Supt Glodon, ASP Hosein and Insp Rampersad. It was led by Ag Sgt Samaroo under the supervision of PC Bowen, with support from officers of the Central Division Task Force.
Meanwhile, between 10 pm on Thursday and 2 am on Friday, officers attached to the North Central Division Task Force conducted a roving road check as part of Operation S.U.M.M.E.R Shield.
Around 12:40 am, officers received a report that suspects wanted in connection with a recent robbery had been seen walking near Scott Street, St Augustine.
A party of officers responded, identified themselves and arrested the men.
The officers then went to another location in St Augustine, where they encountered four more people who were also arrested.
The suspects include two boys, aged 14 and 15, and two men, aged 18 and 20, all from St Augustine.
The other two suspects are men, aged 21 and 23, both from Arouca.
Investigations are continuing.
