A CLEAN-UP operation has been undertaken after the travellers vacated the car park near the Bromsgrove Community and Leisure Centre.
And measures have been introduced to stop future illegal encampments.
The group were there from Thursday and left on Sunday.
They were praised for the £100 they donated to the Afghan refugee appeal and for helping load items on to the coach but they have come under fire for the mass amount of rubbish they left behind when they departed.
Coun Josh Robinson, who represents the town centre on Worcestershire County Council, said on Twitter on Sunday: “They have now left, despite the positives of them giving money and support yesterday to the Afghan refugee appeal the state they left the car park in is unacceptable.
“We have cleaned most of it up this afternoon but awaiting the the district council to pick the rest of it up tomorrow.”
A Bromsgrove District Council spokesperson said: “The site was cleaned and disinfected this morning by the Council’s Place team.
“A temporary solution has been put in place to stop vehicle access to the site until a permanent barrier is installed by the authority’s Minor Works Team.”
