White House on lockdown for second time in less than a week

The official residence of the US president was on lockdown on Thursday for the second time in less than a week after two people threw items over White House fences.

According to the Secret Service, two people threw items over fences on opposite sides of the White House complex – one from the south side and the other from the north – at almost exactly the same time.

The US presidential compound was on a lockdown that went into effect before 3 p.m. and was lifted after about 90 minutes.

One individual threw what is believed to be a cassette tape over the fence on the north side and the other person allegedly threw papers over the fence on the south side.

Both suspects were detained and questioned Thursday afternoon. Secret Service officials say they were charged with “throwing objects – missiles.” US President Barack Obama was in California when the incident happened.

The incident follows another White House lockdown on Tuesday which lasted for an hour and was triggered after an unknown vehicle followed a motorcade bringing Obama’s daughters home through the gates. Officials charged the driver of the vehicle with unlawful entry, a misdemeanor.
