A man was arrested as police seized a knuckleduster and class A drugs as officers broke up a huge illegal rave.
They were pelted with bottles and one person was detained on suspicion of assault as the huge party was busted at a disused warehouse in Bordesley Street, Digbeth, at around 9pm on Saturday, November 28.
DJ equipment was also seized and more than 100 fines issued at the huge music event.
Someone kicked out towards an officer but they were unhurt. A 36-year-old man was arrested on suspicion of assault and later released under investigation.
Police were approached by a woman who also suffered an ankle injury at the large gathering.
Police said they had identified the organisers and were looking at further action as they reviewed footage.
Under coronavirus restrictions, social gatherings between different households indoors are banned. This will also apply when lockdown is lifted on December 2 and Birmingham enters Tier 3.
Condemning the party amid the heightened risk from the ‘deadly virus’, Chief Supt Andy Beard said: “This was not only illegal, but extremely dangerous for both those who attended and officers.
“It’s extremely disappointing some are still not grasping that such events only increase the risk of spreading a deadly virus.
“We’re currently under national restrictions and the region will then go into the highest tier due to the number of Covid cases next week.
“It’s unacceptable when people recklessly ignore the rules and put themselves and others at risk of catching the disease. It’s also unacceptable that officers should be attacked while going about their duties.
“We’ve seized equipment, drugs and a weapon and we’ll be looking to ensure there will be no repeat again.”
