A “bullied” 14-year-old boy was killed by a train moments after he handed over his mobile phone and school bag to horrified classmates.

Sobbing friends screamed “I saw it, I saw it” after Sam Connor lay down on the tracks before being struck at 4 p.m. Monday (local time) at Chertsey station.

More than 50 children and adults from Roman Catholic school Salesian were understood to have been standing on the platform at the time of the tragedy.

Cops were called to usher them away from the horrific scene so body recovery experts could remove his remains from the tracks.

One of Sam’s friends said he was being bullied and would sit on his own in the playground at break time.

It is understood that a scrawled note — believed to be a suicide note — was found nearby.

A family friend told The Sun: “Sam was being bullied at school but I don’t know how. Lots of children are bullied but it must have been horrendous for him to resort to this.”

Heartfelt tributes

Devastated friends have described Sam as “bright and popular” and said the teen was one of the “nicest and most charming” boys at a local breakdancing club.

One posted a heartbreaking tribute on Facebook, alongside a photo of Sam with his breakdancing pals.

He wrote: “Cannot even think of an emotion to describe how I am right now apart from just heartbroken. No parent should ever have to bury their own child. The child should always bury the parents.

“The crying with happiness, the laughs, the dancing will never be the same without you. Rest in peace Sam you absolute legend.

“Breaking isn’t going to be the same with you gone. Hope you’re still dancing out there in the skies.”

Tragic Sam was ‘bullied’

The owner of a convenience store close to the Connor family home in Ashford, about 90 minutes southeast of London, also spoke of his shock at the 14-year-old’s death.

He said: “He was always so polite and a really lovely lad. I just can’t believe what has happened.”

Others have described how Sam was being bullied, which the school has denied.

“It’s horrible. I have friends who were there and saw the whole thing,” one boy told the Daily Mail.

“[He] handed his bag and phone to his friends and then lay down on the track in front of the train.

“Some of the older pupils were really good — they held everyone back and made sure everyone else was safe.

“They said he was being bullied. It’s only four days until school breaks up and you’d have thought he’d be able to get help.”

More than 25 floral tributes have been left on the gates of the station today, with one reading: “So sorry that life wasn’t kinder to you sweetheart. RIP Angel.”

Another friend, Teri Jones, added: “R.I.P little man. Find your happiness in heaven.”

In the wake of the tragedy on Monday, a sweet shop worker said tearful children ran screaming into her store, which is opposite the station.

She said: “It was so sad. Children were running around crying and screaming.

“One young girl came in the shop in tears and was screaming, ‘I’ve seen it all.’

“We looked out and saw the train on the platform and put two and two together.

“The kids on the platform didn’t know what to do.”

Sobbing friends called his name

Horrified witnesses also claimed sobbing pupils had called out Sam’s name after he was struck by the train.

One passenger, who was on the train when it hit the boy, told the Mail Online: “The train stopped very suddenly with only one carriage alongside the platform.

“I thought maybe one of the kids had dropped their phone as they were all looking down at the wheels of the carriage.

“We saw some of the girls starting to cry; we saw some of the boys leaning down, literally on their knees, calling down between the train and the tracks, calling, ‘Sam, Sam.'”

A school spokesman told the newspaper they had “no record” of the boy being bullied and couldn’t make any further comment.

Headteacher James Kibble said the school is “devastated” and will be holding a series of assemblies to help students come to terms with the tragedy.

He wrote: “We were devastated to find out that, following an incident at Chertsey station, one of our Year 9 students died this afternoon.

“This is an incredibly difficult situation for everyone, but knowing the faith, compassion, and strength of our school community, I am confident that we will work together to support one another.

“This will start from first thing tomorrow, and will be holding a series of assemblies to talk to the students about what has happened and how we can collectively come to terms with this tragedy.

“We would ask that our community joins together to remember the student and their family in their prayers at this incredibly sad time.”

The annual sports day was due to take place this week but was canceled after the tragedy.

An educational psychologist and counselors are on site to help the youngsters.

A British Transport Police spokesman said: “Officers were called to Chertsey station at 4 p.m. following reports of a casualty on the tracks.

“Paramedics also attended and sadly a person has been pronounced dead at the scene. The incident is not being treated as suspicious and a file will be prepared for the coroner.”
