A six-year-old Scottish boy sparked panic on his school bus after pulling out a knife and threatening to kill them.
Angry parents say the bus was travelling to the school in East Kilbride last week when the incident happened.
Another pupil is understood to have asked the boy if he was carrying a knife in his school bag.
The youngster then reportedly removed a “large kitchen knife” from his bag before lashing out, saying he was going to stab the boy before murdering “the rest of the school”.
According to parents, the bus driver then intervened and removed the knife.
The mother of the boy who was allegedly threatened told the Daily Record he was “hysterical and crying” when she collected him from school.
She added: “I got a call to pick my son up in the afternoon. I didn’t know anything about this. I was only told he had been suffering headaches all day.
“I found out from a text from another parent.
“I kept him off the next day as he was so worried and wouldn’t sleep in his own bed. He is scared to go back on the bus.”
Des Dickson, South Lanarkshire Council’s head of education, said: “The safety and wellbeing of all children is paramount, and the school have taken a proactive approach seeking to reassure parents who have raised concerns.
“The head teacher and staff are dealing with this matter in a sensitive and professional manner.”
