Greater Manchester Police said the two men pulled their van up to the Khawja Brothers Mini Market in Chorlton Nov. 28 and loaded the vehicle with trees.
The men returned again Nov. 30 and stole another load of trees, bringing the total number of stolen plants to 190.
Police said residents have reported seeing the van selling Christmas trees around Chorlton.
“The shop owners were devastated to discover that 190 of their Christmas trees had been stolen. This is their livelihood and the offenders selfishly put their business in jeopardy,” Detective Constable Trudy Lindsey of South Manchester division said.
“The van has been spotted in Chorlton since, offering people Christmas trees. If you are offered one to buy I would ask that you contact police immediately,” Lindsey said. “If you recognize the men in the CCTV, please get in touch with us and help us to catch those responsible.”
