Students were locked in a library as armed police stormed the University of Lincoln campus.
Some students were told to move out of the way, and others were locked inside buildings, while armed officers arrested a 25-year-old man this morning near the university's library.
Lincolnshire Police has apologised for “any alarm caused” by the arrest - which was in connection with a burglary where a man was assaulted with a pickaxe.
One student, who only gave her name as Emma, told the BBC she had been walking to the library with a friend when she saw 10 police cars. She said she had “never been so scared”.
She added: “We saw all these armed police and a police dog running about and then these university people in Lincoln uniform told me and my friends to run away.”
Around midday, Lincolnshire Police tweeted: “We have arrested one man, aged 25, near to the Engine Shed, Lincoln this morning, on behalf of Nottinghamshire Police.
“We have had a lot of resources in the area and this has caused some alarm. Apologies for this.”
The force added that reports that the man was seen with a handgun were “incorrect".
