Police are appealing for information after a dog walker was left with a suspected fractured spine after he was apparently pushed down an embankment, falling up to 30 feet.
The 51-year-old man was walking his dog in a secluded wooded area at the rear of Warmden Avenue and Southwood Drive in Baxenden between 10.30pm and 11.15pm when he was approached by two men.
One of the men is believed to have pushed him, causing him to fall approximately 20 to 30 feet down the embankment.
The victim sustained injuries to his neck and back.
The two men are described as being in their late teens or early 20s.
DS Ian Procter, of Blackburn CID, said: “There does not appear to be any sort of motive for this attack which left the victim with a suspected fractured vertebra.
"The area concerned is treacherous, particularly in darkness and when wet underfoot, and there is a dangerous drop towards a stream. It is important that the two men involved are traced as a matter of urgency to ascertain exactly what happened.
"I would appeal to anyone with any information that could assist us with our investigation to call 101 quoting incident reference LC-20140712-1868.
People can pass information to police either by calling 101, speaking to a local officer or anonymously through the charity Crimestoppers on 0800 555 111 or on-line at Crimestoppers-uk.org.
No personal details are taken, information is not traced or recorded and you will not go to court."
