Police were called to the Grand Union Canal when a couple of suspicious looking objects were dredged up.

The metal cylinders certainly looked like they could have been unexploded wartime bombs.

But experts soon declared them nothing of the kind, and work on dredging the Slough arm of the canal – from Cowley to Slough – continues.

The £716,000 project will remove about 10,000 tonnes of silt, and plenty of debris such as shopping trolleys is expected.

The cylinders, dredged up last week, were believed to have been found close to the Slough end of the waterway.
