BURGLARS ransacked units as they raided a major industrial estate last night.

Up to 30 units on Nelson's Lomeshaye Industrial Estate were broken into between 10pm and midnight, including Lomeshaye Village Nursery, where CCTV showed the suspects smashing children’s toys up.

Police helicopter and dog units were sent out when the two suspects triggered an alarm system.

The two suspects were found in Lomeshaye Mill by police dog, PD Zorro. They were seen wearing balaclavas, using walkie talkies and one of the men had a large knife.

Officers said stolen goods, including cash and health products, were stacked up next to them and ready to be taken away.

A 32-year-old man from Nelson and 30-year-old man from Nelson were arrested on suspicion of burglary. They remain in custody and will be questioned later today.

Inspector Chris Valentine said the incident would be distressing for the business owners and staff.

He said: "The damage that people have to pay for and the children's toys that have been damaged will be incredibly upsetting for the children and staff.

"Most of them will be unaware until they arrive for work. It's a financial and personal impact."

Anyone who has any information can contact the police on 101 referencing log number 1353 of January 3.
