A man has appeared in court after a suspicious package was sent to a coronavirus vaccine production plant in Wrexham, north Wales. Staff were forced to evacuate from the Wockhardt site when the package arrived on Wednesday morning, and production at the facility ground to a halt while the package was investigated. Kent police said it was “not a viable device”, but it appears to have been intended as an explosive. Anthony Collins, 53, was charged with “dispatching an article by post with the intention of inducing the belief it is likely to explode or ignite”, a spokesman for the force said. The motive behind the incident remains unclear. Collins, of Chatham Hill, Chatham, Kent, was arrested by officers on Thursday morning and remanded in custody. He appeared at Medway magistrates court on Saturday, according to police. At the hearing, he was further remanded in custody and will appear at Maidstone crown court on 26 February. Wockhardt, a global pharmaceutical and biotechnology company, is involved in the production of the Oxford/AstraZeneca vaccine. The firm provides fill-and-finish services, the final stage of production where the vaccine is put into vials. According to its website, the firm has 12 manufacturing plants around the world, with headquarters based in India.
