A Nexus spokesman said: "There was an incident at 7.45am today with a disruptive male passenger at South Gosforth.
"Police were called to remove him from a train.
"The hold up has caused some gaps in service."
A Northumbria Police spokeswoman said: "At 7.30am Metro staff at South Gosforth Metro station called for assistance after a man was behaving in a disorderly manner."
