Ett citat:
"A man has been arrested after a suspicious package was sent to a Covid-19 vaccine factory in Wrexham. [...] Kent Police said a 53-year-old man from Chatham had been arrested on suspicion of sending the package and remains in custody as inquiries continue. It said warrants had taken place on Luton Road and Chatham Hill, Chatham, on Thursday morning. There is no evidence to suggest there is an ongoing threat, it added. On Wednesday police said the package had been made safe and its contents would be "taken away for analysis"."
Det ska bli spännande att höra vad motivet var - något vaccin-relaterat, eller kanske något gammalt groll med företaget i fråga?
