Armed police spent an hour on a Kirkcaldy street on Monday night as they dealt with an ongoing incident.
A large number of officers spent over an hour on Dallas Drive and the surrounding streets between 9pm and 10pm.
A dog handling unit accompanied the armed officers on the scene.
One eyewitness said: “We heard a bit of commotion outside and then all of a sudden there were loads of armed police surrounding the area.
“We were unsure exactly what was going on but the officers were here for around an hour before they left. I think they may have arrested someone.”
Police Scotland has been contacted for comment.
