(CNN) A busy area of central London has been shut down for a second consecutive day, after police found another part of an unexploded World War II bomb.

Soho's Dean Street was blocked off and workers were told to leave their offices again following the discovery on Tuesday.

Construction workers first came across the bomb near the Soho Hotel on Monday, prompting a sizable portion of the neighborhood to be shut down by police and hundreds of people to be evacuated.
