A Wisconsin school district has been put on lockdown after an active shooter tried to enter a middle school on Wednesday.

The Mount Horeb Area School District said on Facebook: 'Community members, there has been an active shooter at our middle school this morning. 

'The individual did not breach entryway. Police department is helping to scope out our building to ensure the safety of our students and staff. I will keep you posted.'

The district asked people to stay away from the middle school.

'We are in the process of activating our reunification plan and further details will be provided.'

A big police presence was seen outside the middle school.

No injuries have been reported.
