The mother of a student who died in Germany, is calling for the investigation into his death to be re-opened.
Erica Duggan says she knows her son's death was not suicide
Jeremiah Duggan, 22, from Golders Green, north London, was found dead near the town of Wiesbaden in Germany after being run over by several vehicles.
Police concluded it was suicide but Mr Duggan's mother believes he was murdered.
Erica Duggan told BBC London she received a call from her son in the middle of the night the day before his body was found.
She said: "The phone went and he said 'Mum, I'm in terrible trouble' and he said 'I'm frightened'.
"And I said 'Tell me Jerry, tell me' and again it was as if he couldn't tell me what it was."
Friends of Jeremiah Duggan said he loved life in Paris
The 22-year-old, who was at university in Paris, had travelled to the town near Frankfurt for an anti-war conference with a group of people who worked selling the newspaper Nouvelle Solidarité.
Mrs Duggan believes there are unanswered questions over her son's death and wants German authorities to re-open their investigation.
She said: "Was he chased? Was he pushed? Was he threatened? What happened to make his mind be in this state of fear?
"What was he so frightened of? What was going on his mind? I know it wasn't suicide."
Friends of Mr Duggan said he loved life in Paris and had been making plans for the future.
