At around 11.39am officers were called to reports a man had entered Nationwide on New Street saying he had a firearm before taking around £2,000 in cash.
No one was injured during the incident and the man left the scene before officers arrived.
Yesterday (Wednesday 26 August) officers arrested a 43-year-old Wolverhampton man on suspicion of robbery. He remains in police custody as enquiries continue.
He was also arrested on suspicion of robbery in connection with an incident at the Albrighton Co-op on Friday (21 August), and suspicion of burglary relating to a break-in at a café in Wellington on Friday 3 July.
Detective Sergeant Craig Ryder told us: "We understand incidents of this nature can be concerning for local communities; however, I would like to reassure residents a swift investigation has led to the arrest of a man in connection with Monday’s robbery. Thankfully, no one was injured during the incident.
"Our enquiries remain ongoing while the suspect remains in custody, and I would like to thank the public for their support and patience while officers continue their work."
