(CNN) The small English cathedral city of Salisbury at the center of an international investigation into the Novichok poisonings is once again in the spotlight.

A 45-year-old man was arrested Thursday for trying to steal a copy of the Magna Carta from the city's famed cathedral. The 803-year-old document is widely considered one of the most important documents in history.

The man smashed the glass box that houses the document -- considered one of the most important in British history -- at around 5 p.m., according to a Wiltshire police statement.

It was not damaged and no one was injured in the incident, police said.

The culprit, who has not been named, was later arrested for attempted theft and possession of "an offensive weapon and criminal damage."
