The White House was on lockdown on Thursday after a man jumped the fence onto the lawn, said local media reports.

The jumper was immediately caught, said the US TV network CNN.

Despite the immediate capture of the intruder, the presidential compound was reportedly still on lockdown as the US Secret Service carried out security check of the compound.

According to US President Barack Obama's public schedule, the First Family was at the White House to celebrate the Thanksgiving Day.

This was the second lockdown for the White House in the past seven days. On Saturday, a brief lockdown was put on the White House after a woman threw an apple core over the fence line of the South Lawn.

Thursday's lockdown was also the latest incident of a series of intrusions into the presidential mansion in the past two years, which finally caused the Secret Service to add metal spikes onto the fence surrounding the White House in July.

So far, the most concerning fence-jumping incident happened in September 2014, when a knife-wielding man with psychological problems jumped over the White House fence and dashed deep into the complex till he reached the doors of the East Room.
