Police Scotland confirmed that three men aged 18, 28 and 29, and a 21-year-old woman were arrested and charged during the demonstration.
Chief Inspector Derrick Johnston said: “We have a legal duty to protect the rights of people who wish to peacefully protest as well as those affected by protest activity. However, officers were met with an unacceptable level of hostility and resistance today.
“One of our officers was bitten. Assaults are not part of the job and will not be tolerated, and we were fortunately able to arrest the individual responsible.
Thales, a French multinational company that designs and develops technology for the defence industry, insists that claims the site supplies the Israeli military are false.
Company says site does not supply Israel
A spokesman for Thales told The Telegraph that the factory in Glasgow produces specialist technology such as periscopes for use by the Royal Navy and British Army but is not involved in manufacturing drones.
Last week, arrests were made after similar protests at the U-TacS factory in Leicester, a joint venture between Thales and Elbit Systems, an Israeli defence contractor, which does manufacture drones.
However, Thales said the Watchkeeper X drones produced at the plant are used solely for reconnaissance by the British Army and that the Leicester site does not supply Israeli forces.
In an earlier statement, Thales said of the protests: “While those outside our site in Glasgow have the right to protest peacefully, we will work with authorities to prosecute anyone who threatens our employees, our property or our important work for the UK Armed Forces.”
