Man Charged After Melbourne CBD Sent Into Lockdown

A man has been charged after allegedly driving erratically and bringing Melbourne's CBD to a standstill Wednesday afternoon.

Streets were placed in lockdown  after a driver was seen and filmed standing on top of a silver sedan and yelling into a crowd of spectators.  Witnesses claimed the man was yelling for police to 'stop him'.

Victoria Police officers responded to the incident and asked everyone to avoid the area.

Police later confirmed a 26-year-old man was arrested. It's alleged the man was driving erratically along Flinders St about 1.50pm.

He has since been charged.

It's understood nothing suspicious was found.

A number of road closures were put in place during the police operation, including Flinders and King St, Flinders St and Market St, Queensbridge, William St and Flinders St.
