Southampton Pays Most Compensation For School Injuries
A Heart investigation has found that Southampton paid out more than any other council in the country in compensation to pupils and teachers last year.
The total bill for slips, trips and falls was £305,833.
It included a payment of £100,000 to a pupil who fell on the stairs at his school in the city, while a teacher got the same payout after getting hurt by a piece of metal in a cupboard.
West Sussex County Council paid out £38,738 and Portsmouth City Council's compensation bill was £17,957.
In comparison, the bill for Dorset County Council was only £1,759.
In total, councils paid out nearly £2 million (£1,966,187.37) to 468 teachers and 305 pupils last year. On average that equates to £2,000 per teacher or pupil.
11 pupils got £237,766.88 for 'falling on school property'.
Violent crime was up 37% in the last year. Police say it's mainly due to a change in how offences are recorded.
