Security at the White House was again breached Sunday after a 4-year-old toddler got through a security barrier on the property.

The incident happened Sunday afternoon when security agents rushed to the north lawn with their weapons drawn and checked out the area.

They discovered that the toddler had managed to climb under a temporary barrier along Pennsylvania Avenue outside the White House gate. The barrier looks similar to a bike rack, officials said, but is meant to keep pedestrians away.

It was not immediately clear how the child got through the secured area. The child was reported to be fine and reunited with the parents. Brian Leary, a spokesman for the U.S. Secret Service, said Monday that the child “didn’t get through the fence” and onto the lawn.

It isn’t the first time there was a small child has gotten near security areas of the White House. In August 2014, a toddler squeezed through a fence in front of the residence.

The latest incident comes as security at the White House has come under the spotlight.

In March, two senior Secret Service agents were said to have driven a car into White House security barricades after drinking at a late-night party. And in January, a small drone found on the White House lawn caused concern.

There was also an incident last October when a man jumped the White House fence and raced through much of the mansion’s main floor.
