26-year-old Obanyeli Jesse Chima was an international student from Nigeria who had just finished his master's degree in Public Health in London. He was waiting in a lounge to meet friends for a joint birthday celebration when he said he needed to step outside for some air. His breathing quickly deteriorated. Despite using three different inhalers he had with him, nothing helped. His friend called an ambulance, but while she was still on the phone with the operator, he collapsed. His friends started CPR right there on the street, guided by the emergency operator. Paramedics spent about two hours working to stabilise him before rushing him to hospital. He was placed on life support. At first, medics hoped he would only suffer memory loss. But two days later, doctors confirmed there had been no improvement and tests showed he was brain-dead. Jesse was just 26. He leaves behind three siblings in Nigeria. He was known as a passionate Chelsea FC fan who had even worked at the club. His friend Eva said his family had been saving money to fly over for his graduation. "His family had saved money for his graduation, and now that money needs to be used to bury their child," she said. Friends are now raising money to transport his body back to Nigeria so his family can lay him to rest. A GoFundMe account has been created. gofundme.com/f/help-bring-ch…
