Alleged incidents of violence by pupils in the county have more than doubled in three years, according to police figures.
Officers were called to schools more than 3,500 times in 2008. Incidents included 121 allegations of attempted or actual violence, up from 52 such cases in 2005, according to figures released to the East Anglian Daily Times.
In 2007, there were 97 allegations of violence, a 25 per cent rise in a single year.
Accusations against pupils under 15 include 55 asaults involving actual bodily harm, seven of grievous bodily harm and three threats to kill.
Seven allegations involved racial assaults or racially aggravated harassment. There was a further claim that a pupil had administered a poisonous or noxious substance.
Nick Wilding, the young persons' health and safety manager for Suffolk, said: "Sanctions available are wide-ranging, from normal basic disciplinary sanctions ... through to temporary or permanent exclusion.
"If an event is sufficiently serious to warrant referral to the police, it will be up to the police to determine the extent of any action taken, including legal action if appropriate." dm.
