Unhappy : School headteacher Dan Philpotts has criticised the sweet shop for opening at 7.30am . A headmaster today criticised a sweet shop which opens at 7.30am on weekdays - because it is leaving his pupils ‘ hyperactive ’ in class . Parents have been asked to stop their children visiting the shop in Radcliffe-on-Trent on the way to school after it emerged some students were spending their dinner money on sweets . South Nottinghamshire Academy principal Dan Philpotts , 40 , hit out after the Sweet Cottage opened 1,300ft ( 400m ) from the school gates less than two weeks ago on February 28 . The married father-of-two said the shop - which opens from 7.30am to 4.30pm on Monday to Friday - is causing some pupils to become ‘ disruptive ’ because they are high on sugar . Mr Philpotts added : ‘ This has escalated out of control . It ’ s crazy . I am just looking out for what is best for our pupils . There hasn ’ t been one specific incident that sparked this . ‘ But students have been coming in late , and just generally becoming hyperactive and causing disruption . The shop is not prepared to acknowledge the effect it is having. ’ The headmaster , a former Wolverhampton Wanderers youth footballer , insisted that he wanted to continue working with the shop , but it would carry on opening at 7.30am each day . He continued : ‘ We are asking parents to speak with their children about being sensible with their sugar intake and how they spend their dinner money . Opening hours : The shop is said to be causing pupils to become ‘ disruptive ’ because they are high on sugar . Letter : Mr Philpotts wrote to parents of South Nottinghamshire Academy pupils to warn them about the shop . ‘ We will continue to inform and work with parents to avoid any unnecessary disruption during school hours which impacts on pupils ’ behaviours and learning. ’ Since the shop opened , teachers have reported pupils coming in with stained mouths and hands from the sweets they were buying and then eating . But the owner of the Sweet Cottage hit back , saying children have always taken sweets to school . He said : ‘ When I was a kid I always took a bag of sweets to school . The headteacher was not invited to come to the shop , he came of his own accord and he upset customers . Local shop : The Sweet Cottage ( in red ) opened just 1,300ft from the school ( in blue ) less than two weeks ago . 'Working with parents ' : The school caters for 520 pupils aged 11 to 18 and has been rated 'good ' by Ofsted . ‘ It is just a coincidence that we open at 7.30am . We are not trying to entice schoolchildren in - and we will be opening at the same time during school holidays. ’ In his letter to parents , which was sent out last Friday , Mr Philpotts urged parents to back the school ’ s unofficial boycott . It stated : ‘ It is important to note that , as an academy , and in our role in loco parentis to your children , we do not object to sweets per se . ‘ But we do object to students filling up on sweets before the school day has even started. ’ The school caters for 520 pupils aged 11 to 18 and was rated ‘ good ’ by watchdog Ofsted in its last inspection two years ago .
