Around 12 cars parked on the same street were scratched and keyed as their owners slept.
The cars were found damaged on Monday morning on Harcourt Road, Accrington, police confirmed.
Retired resident Mr Graham Lowe, 62, whose Peugeot was scratched, said: "One of my neighbours called me about 9.30am and told me the police were here and that I should check if my car had been damaged. I quickly got came out and saw that it had.
"I can't understand these idiots. Usually I get wound up about things like this. I haven't done yet but when it sinks in I will.
"It's never happened to me before and I have been here for 17 years. We don't have any problems around here.
"I didn't get to bed until about midnight and I'm usually always aware of anything unusual happening outside my window. For some reason I had the window closed and the radio on before I went to bed. I was kicking myself when I found out because if I had the window open I might have seen them and done something about it.
"It's just a mindless thing to do. I don't know how much its going to cost me yet," he added.
Neighbour David Climpson, 66, was unaware his Honda Jazz had been scratched until being informed by the Observer.
He said: "The last time I used the car was about 6pm on Sunday. I didn't know my car had been done. I saw the police in the morning but didn't know what was going on.
"This is not the kind of thing that happens in the neighbourhood but all you need is somebody going up the road with a key and that happens.
"It's just drunken mindlessness. I'm quite shocked something like this has happened."
The incident is believed to have happened sometime after midnight on Sunday, October 23 and the early hours of Monday, October 24.
A spokeswoman for Lancashire Police said: "We can confirm that we have received reports that a number of cars were damaged on Harcourt Road and we are investigating. Any suspicious behaviour in the area or any information can be passed to police on 08451 25 35 45."
