Royal Mail has intercepted a "suspicious" parcel that was found to contain illegal drugs.
Postal workers stopped the package in Poole, Dorset, and found that it contained cannabis that had been hidden with cold and flu tablets.
Dorset police have now collected the parcel and are investigating it.
The address the package was sent to is also "now of interest" to officers, as well as the Royal Mail.
Poole Police posted an image of the seized package to its Facebook account, showing a quantity of the Class B drug wrapped in cling film alongside a box of max strength cold and flu tablets.
Police said in a statement: "Royal Mail have intercepted a suspicious Parcel. Poole Neighbourhood Policing Team collected the parcel. The parcel contained Drugs.
"We are now investigating this. Cannabis is a class B drug meaning it is illegal to possess."
It added: "Anyone found with the drug could be imprisoned for up to five years while supplying it can be punished with 14-year jail sentence or an unlimited fine.
"Importation offences carry a far greater penalty. The address this item was sent to is now of interest to both Royal Mail and Dorset Police.
It's not the first time that Royal Mail has discovered drugs and other illegal items sent through the postal system.
In July last year, items including crack cocaine, spice, sleeping pills, and a butterfly knife were found in intercepted packages at a Royal Mail sorting office in Cambridgeshire.
Posting about the find on social media, Cambridgeshire Police said at the time: "If you're missing some post, we might just have it at Thorpe Wood Police Station in Peterborough.
"Officers attended the Royal Mail sorting office in Werrington on Thursday and the staff there intercepted 46 packages."
