A 31-year-old man has been arrested by West Midlands Police in connection with the investigation into threats to kidnap and murder a police officer.
Counter-terrorism officers arrested the man at a property in the West Midlands on Tuesday afternoon.
The arrest comes after West Midlands Police issued an alert to officers after a “credible” tip-off was made to police on Monday.
In response to the threat, West Midlands police implemented a number of increased security measures to reduce the risk to its officers, including urging them to wear plain clothes when travelling to and from work.
Police reassured the public that its officers would patrol and respond to emergency calls “as normal” despite the threat.
After the arrest, the force remains on a “severe” level of terror alert.
Nationally, the threat level to police officers was raised to substantial in October, and the national security level remains classed as “severe”, denoting that a terrorist attack is highly likely on UK soil.
