Builders working on a property in Eccleston Park foiled an attempted burglary at a nearby home.
The workers went to investigate after hearing the sound of breaking glass and stumbled across a gang of raiders attempting to force their way into the house.
One of the crooks, who was using a walkie-talkie, fled and jumped into a waiting Mercedes estate which then sped off in the direction of St Helens town centre.
The incident took place at 2.40pm on Wednesday, August 27 on Tern Way.
The man seen in the garden attempting to break in was dressed all in black and wore a balaclava. The suspect driving the vehicle is described as white, with a large build and aged around 30.
He was wearing a black cap and dark clothing.
DC Roy Waller said: ”This incident has left an elderly disabled woman extremely shaken and in shock. Thanks to the rapid action of the builders, the suspect did not manage to gain entry and was made to leave empty-handed.
“I would like to appeal to anyone who may know who these two men are or have any information to contact the police.”
Anyone with information about this incident is asked to call 101 or Crimestoppers anonymously on 0800 555 111.
