A four-year-old child climbed under a temporary bike rack along Pennsylvania Avenue triggering Secret Service to put the president residence under lock down for a few moments . The incident is the second lockdown in Washington only a day after a man shot and killed himself on Saturday. The man died after shooting himself on the west front of the Capitol building just after 1 p.m., Capitol Police spokeswoman Kimberly Schneider said. No one else was hurt. Capitol Police Chief Kim Dine said the man had a backpack and a rolling suitcase, triggering an hours-long lockdown, and a sign that said something about 'social justice.' Witness Robert Bishop told CNN it said something about taxing the '1%.' Bomb squad members respond to reports of a suspicious package on the West Front of the US Capitol,  on Capitol Hill on Saturday. A man carrying a backpack and rolling suitcase shot himself while carrying a sign about taxation. Authorities do not believe there is a terrorism connection . Robert Bishop of Annapolis, Maryland said he was biking near the steps of the Capitol when the suicide happened. Bishop didn't witness the suicide but said there were about 60 people in the area, and that some of them did, including a girl and her mother who immediately began crying afterward. Bishop said another witness told him and a police officer that the man who killed himself held up a protest sign about taxation just before pulling the trigger. The lockdown came during Washington's annual Cherry Blossom Festival, which attracts thousands of tourists during Washington's busy season. Congress has been on spring recess for two weeks and lawmakers are set to return to work Monday.
