Officers scoured the area but neither the van or the suspects were traced, and no victims have come forward so far.

The force is still investigating and has asked anyone with information to call 101, quoting ISR 642 of Monday 13 March.

Locals reported being disturbed by the helicopter overhead around Meriden and concerned by the large armed police presence.

A number of people shared their confusion and hopes that everyone was ok.
