A bus driver was injured on Wednesday night after missiles, including fireworks, were thrown at his bus in the Charleston area of Dundee.
It is understood the driver was not seriously hurt but Police Scotland have confirmed they are investigating the incident.
A spokesman for the force said: “We have been made aware of the incident and will be making relevant inquiries.”
While Chief Inspector Nicola Russell slammed those for “tying up vital resources”.
The incident happened during what is understood to have been a night of trouble throughout the city.
Xplore was forced to withdraw several vehicles in parts of Dundee because of what they described as “antisocial” behaviour.
Meantime, it is understood that police are investigating various hotspots of trouble caused by youths in several areas, including Charleston and Whitfield after receiving a number of calls from concerned residents.
One resident in Whitfield reported that kids there were “running riot”.
Another Whitfield local said that people were scared to walk in the area last night because of what was happening.
A spokeswoman for Xplore said: “Due to antisocial behaviour in Whitfield, when vehicles were being struck by missiles, we were forced to withdrawn services 9/10 and 33 from Lothian Crescent.
“We also had to withdraw services 28 and 29 due to fireworks and eggs being thrown at buses resulting in a driver being injured.
“Throwing any object at a bus, building or another vehicle is an extremely dangerous and criminal act.
“It’s disappointing that we have again had to temporarily withdraw services, however safety is our first priority – our drivers deserve to work in safe conditions and our passengers need to travel safely too.
“All incidents of antisocial behaviour involving our buses have been reported to police and we will work with them to try to identify and prosecute those responsible.
“As far as I know, the services are back to normal this morning – it was only a temporary diversion – and we understand the driver wasn’t seriously hurt.”
CH In Russell said: “Unfortunately, our officers were called to a number of incidents of anti-social behaviour across the city involving youths throwing items including eggs and, more recklessly, fireworks.
“It is very disappointing that these individuals feel the need to spoil an enjoyable evening for others through their own thoughtless and at times dangerously reckless behaviour.
“This ties up vital resources which are taken away from dealing with other important matters requiring police attention.
“I would again ask parents across Dundee to be aware of what your children are doing if they are out during the evening. Know where they are, who they are with, and what they are up to.
“Officers will be conducting high-visibility patrols across the city, and will be giving added attention to the areas we are most frequently called to for incidents of this nature. Anyone found committing offences or behaving in a dangerous or reckless manner will be dealt with appropriately.”
North East councillor Brian Gordon said: “It’s scandalous that missiles are being thrown at buses, endangering the life of drivers and their passengers.”
