A criminal investigation is under way after items were fly-tipped outside Dundee recycling centres during the bin strikes.
Pictures taken by The Courier earlier this week showed huge piles of waste left dumped at the gates of Baldovie and Riverside recycling centres.
Both sites were shut for eight days due to the industrial action and reopened on Thursday.
Signs have now gone up outside the centres which state: “Council aware. Fly-tipping crime investigation in progress.
“Area subject to ongoing monitoring.”
It comes after reports that officials had been going through the waste dumped at the sites earlier this week in an attempt to identify the households responsible.
Council leader John Alexander previously hit out at the mess left behind during the strikes.
Dundee City Council has been approached for comment on the nature of its investigation.
Meanwhile long queues have built up outside recycling centres in Tayside since they reopened following the strikes.
Dundee City Council says it is only accepting general waste at the centres for now.
A second wave of strikes was planned to get under way in Dundee, Angus and Fife on Tuesday and Perth and Kinross on Wednesday.
However, those have now been called off after a new pay offer was put to staff.
Fly-tipping: What are the penalties?
Scots can face stiff fines for fly-tipping, with the most common being a £200 fixed penalty notice.
But if the case goes to court then offenders could be fined up to a maximum £40,000.
In the most serious cases, the courts can imprison people for up to a year.
