Are you sure it's not paranoia/scarmongering? Seems really petty. Who is this "someone"? probably someone who likes getting others paranoid. What are they saying happened when the police visited? Are they saying they got their phone and computer confiscated? How does this "someone" know their parcel was seized if they got no customs letter, or nothing? I got paranoid as my 2kg (small amount in comparison to the huge consignments that reach their destination) has been sat at Heathrow since 4
