Doctors call on schools to fade out of their final hours to cope with an increase in violent attacks on school children, including stabbing.
A significant increase in knife attacks has led medics to change school hours so that students do not all leave at once.
Dale saw three stabbings in one terror incident last month during a tea-time brawl allegedly involving young people, some of them schoolchildren.
Last Tuesday, a young woman was attacked, following a gathering of 50 people, according to one witness.
A new report, published by the BMJ Open Medical Journal, examined medical records of under 25 patients for stab wounds in London and found that there is a "significant record" of knife attacks at 16 under 16:00 to 16:00.
Medical also calls for a visible police presence at the train and bus stations after school, according to a Daily Mail story.
The authors of the report wrote that "in view of the peak of the incident at the end of the school day, an attractive option is rapid school release times, which can be coupled with an overt deterrent by law enforcement at transportation centers, restaurants and other areas of the school community after school."
They added: "Most of the stabbings during this period on school days took place within 5 kilometers (3 miles) of the house.
"Interpersonal violence with knives is a major public health problem."
Between 2004 and 2014, the number of stabbing wounds in London hospitals increased by an average of 25% annually.

The researchers, led by doctors at Barts Health NHS Trust in London including experts from the London Ambulance Service and the South East Coast Ambulance Service at Newcastle University, said schools must do more to help.
According to them, knife attacks have risen dramatically in recent years – and that about 22 percent of those under the age of 16 whose agents were attacked in the afternoon at school.
The report added: "The sharp increase in injuries between the ages of 14 and 16 shows that educational programs and other preventive interventions are best communicated in primary or post-primary education.
"We have shown that the resulting assaults and penetrating injuries occur in patterns related to separate age.
"Specifically, the period immediately after school constitutes a large proportion of cases in children, and these occur mainly close to home and school.
"This represents an opportunity for targeted prevention strategies for this population."
