A father says it's a "disgrace" that coronavirus testing kits, that apparently had been used, were delivered to his home.
Community testing is being carried out in Walsall, following the discovery of the South African variant of the virus.
Andy Witton claimed two out of five tests delivered to his home appeared to have been used.
Walsall Council said "this is the first indication anything may have not gone to plan".
Last week, residents in the WS2 postcode area were urged to get tested.
Mr Witton said his partner, Tracy Patel, opened the first one on Monday.
He added: "Because it was sealed, we thought well obviously it's sealed, open it up, because we ain't never done a test before.
"Then you had the bottle, with the swab inside... we was about to take the top off when my daughter come in and she said 'dad, they've been used'.
"I just think it's a disgrace, I think (an) absolute disgrace."
