Two members of the center’s staff were slightly injured. Counter-Terrorism Police South East (CTPSE) said its detectives were “working hard to establish the exact circumstances, including the motive, surrounding this incident” and had followed “a number of lines of enquiry”.

Detective Chief Inspector Ollie Wright, head of CTPSE, said the attack on the center was a “traumatic incident for all involved and the wider community”. “heinous crime” He added: “We understand that when counter-terrorism policing is involved, it can be a concern for some people, but I would like to reassure people that there is nothing to suggest an ongoing wider threat at this time. “What seems clear is that this despicable offense was targeted and possibly driven by some form of hate-filled grievance, although this may not necessarily meet the threshold of terrorism. “At this point, the incident itself has not been ruled a terrorist attack, but that is being reviewed as the investigation progresses.”
