=============

FIRE CREWS have been battling a blaze at a disused building in the town park.

YH understands it is the former Paradise Lodge that sits off Park Lane in the town park.

0400 hrs: Crews continue to work hard and the fire is nearly out.

They are using an aerial ladder platform and a drone to deal with any hot spots.

Hertfordshire firefighters have left the incident and three of our crews remain on scene.

Essex Police have set up a cordon.

The roof of the building has collapsed.

An investigation into the cause will take place later this morning.

Station Manager Steve Kirkham praised crews for their work, especially those from Harlow and Old Harlow Fire Stations who were first on scene.

He said: “Their quick actions prevented the fire from spreading, protecting the block of flats nearby.”
