Police investigating damage caused by "industrial strength" fireworks over the weekend said there were three more incidents on Monday. A phone box and a car were badly damaged by fireworks in Gravesend, Kent, on Sunday night.
Kent Police said three more incidents had happened in the town on Monday night - damaging two more vehicles and another phone box.
They said they were keen to bring the "spate of incidents" to an end.
Officers said they were investigating the incidents in connection with a series of cases across the county.
'High-visibility presence'
They said each time the fireworks used appeared to be intended for trade-use only.
Monday night's incidents all happened in the Palmer Avenue in the Kings Farm area of Gravesend, where one of Sunday's attacks also occurred.
Kent Police said they employed a "high-visibility presence" in the area, which stayed in place until the early hours of Tuesday.
Officers made a number of arrests while there, for offences including theft from vehicles, shoplifting, public order offences, assaulting a police officer and obstructing a police officer.
Further inquiries
Several of those arrested were children.
A police spokesman said: "We are taking co-ordinated and concerted actions to bring an end to this spate of incidents.
"Our over-arching concern is for the safety of the public and those people who have set off these fireworks, whose behaviour is putting them at risk."
Police said an 18-year-old man from Gravesend arrested following Sunday's damage was released on bail on Monday, pending further inquiries.
