THE White House is on lockdown today after a suspect tried to jump the south fence and a suspicious package was found.

The US Secret Service said it has a suspect in custody but is still investigating the package.

The south fence line to the building has been shut down after the person tried to leap the barrier around 9.30am local time.

The White House was also dramatically locked down in March - while Donald Trump was inside - after a suspicious package sparked a bomb alert.

The man reportedly approached an officer half a block from the White House and made a 'suspicious' comment while holding a package.

Cops detained the suspect and seized the package.
