The police helicopter was called out to hunt for a suspected burglar following reports of a break-in in Chorley, say police.
Officers attended the Thirlmere Road area on the morning of Sunday, May 14 following the reports.
A police spokesman said that despite attempts to pursue the suspect using dogs and a helicopter, he still managed to escape officers.
PC Craig McCabe said: "We were responding to reports of a burglary that occurred in the local area.
"The offender made off and we believe that we located him nearby. Once he realised that police were on his tail, he ran off into nearby gardens and started to jump over garden fences.
"Although we managed to contain the area quite quickly to wait for assistance from our “noisy” helicopter and just as noisy police dog, it would appear that he managed to evade us.
"What I would say to the person who decided to run away is that we now have some of your personal property. If you would like to call into Chorley Police Station to collect this, we will be more than happy to discuss this matter with you.
"Failing that, I’m pretty certain our forensics colleagues will find your DNA on it. We also have you on CCTV.
"If anybody has any information that may assist us with our enquiries then please contact us."
Anyone with information can contact police on 101 quoting log reference LC-20170514-0442.
