Police confirmed they are looking at five incidents.
A 46 year old man has been arrested West Midlands Police for possession of an offensive weapon.
It's after a large crowd gathered in Bordesley Green last night.
Superintendent Emlyn Richards from Birmingham Police, said: "I appreciate these are incredibly worrying times for communities. This is a time for communities to unite and support each other and we are working together to make sure communities are fully supported and our response is coordinated, proportionate and responsive.
"We are really proud of the strong links we have with communities across Birmingham, and as always, we have officers ready to police and protect the West Midlands.
"My plea to communities is to be extremely mindful of the incredibly harmful spreading of misinformation on social media at the current time, do challenge what you see online, report where appropriate and consider the source of the posts. Always go to trusted sources for your information which includes news outlets and through our social media channels."
