Workers are cleaning up the debris across the floor of the Costa Coffee branch inside Lincoln Odeon after the ceiling “caved in” over the weekend.
It had been suggested that the roof had caved in before being discovered by passers by on Sunday, June 7.
However, a worker on the Brayford Wharf North site told The Lincolnite on Monday morning that water damage had caused the mess they were clearing up.
Nobody was hurt as there was no staff inside the premises at the time.
Pieces of plasterboard had been seen spread across the furniture and floor, and chairs and tables were tipped over at the weekend.
The clean up continued on Monday morning with at least two workers on site.
