Witness Alexander Lees, 22, a former pupil who now works next door to the school, said: 'The staff car park was locked up, which it never is, and the police weren't answering questions.

'There were about four cars and a van, and after the pupils left 11 or 12 police officers walked out to the police van. Apparently it happened on the elevated walkway where people walk between classes.'

Parents arriving at the school today to find out what was happening were not allowed to enter the site, which was in lockdown.

Around 12 police cars, a dogs van, a riot van and a rapid response ambulance were at the scene in the wake of the incident.

One woman, who did not want to be named, said everyone was shocked and all the parents were 'panicking'.

Local resident Richard Karasek, who lives opposite the school, spoke of his shock.

He said: 'We've lived opposite the school for 15 years or more and never really had much of a problem with noise or anything here. But this is awful.

'All my three children went to Cults Academy and Cults Primary too. Nothing like this has happened before, I am sure there's been altercations with teenage boys but nothing like this.'

The 62-year-old said he arrived home from work to find the police carrying outside investigations inside the school building.

He said: 'It's very alarming. It is not something you would expect. The biggest question is why would somebody go to school with a knife in the first place.

'It is an isolated incident albeit a very tragic one. Two families lives have been ruined - it's terrible.'

Headteacher Anna Muirhead told a press conference at the school this evening: 'Pupils and staff are in a state of total shock. The boy involved was a very gentle, caring pupil, with a lot of friends
