A homeless teenager who friends say was moved from Brighton after being evicted from a hostel for bringing friends round died last week after falling from Eastbourne Pier.
Callum King, who was just 18, fell from the pier on Friday at about midday. He was pulled from the water by paramedics but sadly died at the scene.
Friends say he had been struggling with mental illness, and being moved from Brighton to Eastbourne had left him isolated.
Daniel Harris, founder of the Emergency and Temporary Housing Residents Action Group (Ethrag) said that he had been in contact with Callum, who was a member of the group.
He said: “Callum slipped through the net. It’s really tragic. The family is grieving at the moment and the can’t understand how this happened.
“It’s an absolute disgrace. The family just want to know what happened.”
Mr Harris said that Callum had been evicted from the privately run temporary accommodation flats at Percival Terrace after breaking the no visitor rule, despite his fellow residents’ pleas to the management to let him stay.
He moved a few more times in Brighton before eventually moving to Eastbourne – miles away from his friends in Brighton and family in Worthing.
Ethrag is now calling for a full council investigation into how he “slipped through the net”.
A council spokesman said Brighton and Hove City Council were unable to comment before an inquest had been held.
A police spokeswoman said: “The man who died after falling Eastbourne Pier on Friday (5 May) has been identified as 18-year-old Callum King of no fixed address. A date has not yet been set for the inquest.
