POLICE today vowed to take action against protestors who forced a city bank to close.
Officers said they are studying CCTV footage from the Barclay's Argyle Street branch, which pro-Palestine protesters occupied on Saturday afternoon.
The group were rallying against the bank's investment in Raytheon, which has been linked to the Israeli military.
Terrified staff called in the cops after they were forced to retreat to the bank of the branch.
Witnesses said the group of around 20 protestors, who had loud speakers, entered the bank at around 1.30pm on Saturday.
Chief Inspector Mark Sutherland said: "I am absolutely committed to facilitating lawful and peaceful protest within the city centre.
"On this occasion, however, numerous members of the public were prevented from using the banks facilities.
"I am equally committed to ensuring that people who work and visit the city centre can do so without fear or intimidation.
"An inquiry has been launched to look at the full circumstances of Saturday's demonstration and if appropriate then further action will be taken against those involved."
During the protest, the bank was forced to cease trading. After almost 30 minutes, the protestors were ushered outside by police.
Witnesses have been asked to come forward as the police probe continues.
In September, six pro-Palestinian activists were arrested following a demonstration at the premises of defence systems firm Thales UK.
Members of Glasgow Palestine Action climbed onto the roof of the building in Govan and hung a Palestinian flag and a banner reading Stop Arming israel.
Further protesters blocked the gates.
The group said the action is in response to the recent israeli bombardment of Gaza.
Activists said Thales was being targeted for its relationship with Israeli defence company Elbit Systems.
