BRAVE nursery teacher Lisa Potts' back, arms and skull were badly slashed as she shielded toddlers from a crazed knifeman.

Monster Horrett Campbell attacked the 22-year-old teacher's class in Wolverhampton last July. But now Lisa has made a full recovery to launch a local campaign to improve security in schools.

She was at Lancashire Constabulary's Hutton headquarters this week to promote a video on security advice being sent free to more than 900 headteachers in the county.

Lisa received 11 bravery awards following the attack. Giving her backing to the new security video, she said: "My school now has high fencing, CCTV, entrance buzzers, personal alarms and panic buttons.

"We must do everything to stop this happening again, but the children go home at the end of the school day which is when the attack happened. Nothing could have prevented Campbell from getting in."

Lisa recalled the day she faced the frenzied knifeman: "I thought it was a plastic knife at first but when he slashed the children's faces, I realised it was real. My instincts were to protect the kids."

Now security cameras, panic buttons, personal alarms and 12-feet-high fences could become the norm for Preston schools.

Police say the video is aimed at reducing less serious crimes.

Sergeant Steve Saddington said: "We don't want to turn schools into fortresses but staff and pupils need protection from vandals and thieves."

The video has been funded by advertisers through Preston company Avenham Media, and will also be distributed to police forces nationwide. The Lancashire Constabulary has plans to produce more security videos for hotels, hospitals and clinics.
