EYE drops that police say are "potentially harmful" have been stolen from a business in Bury.
The two locked security boxes were stolen in a burglary at Holcombe Precinct, in Holcombe Brook, at about 5.30am on Thursday.
One of the security boxes was later found in Hawkshaw, but with the contents missing.
Police are now asking the public to report any sightings of a 30cm by 20cm blue metal box that was stolen, or the drugs that were held inside.
Shaun Dwyer said: “The packages are described as being three lilac or white cardboard boxes covered with the manufacturer's name Bausch & Lomb, each containing 20 vials of an anaesthetic eye drop.
“The vials are made of opaque plastic, have Prox Fln printed on them and contain a yellow-coloured liquid which is classed as a poison and can be harmful in large doses.
“The others are three small bottles of Chloromphenicol, a clear liquid which is classed as a drug.
“If you have seen these, or know of anyone who may have them please contact us.”
