RELATED: Second violent act reported against Rep. Brady
Bob Brady was not home at the time of his incident, but his wife was.
In an interview with Action News, Debra Brady described what happened.
"It was very scary," Debra Brady told Action News. "I was watching channel 6 news at 12 noon and then when it went off, so did my cable. And I looked outside and I saw three guys walking past my window."
"One guy went over to try to get the sliding screen off," she continued, "and I went up to the window and went face-to-face and I banged on the door. And they all looked at each other and took off," she said.
Bob Brady said the men were wearing some kind of facial masks and hoodies, so his wife was not able to identify the three individuals.
Neighbors saw them fleeing the scene in a dark colored, possibly black vehicle.
"You feel violated," said the congressman. "Thank God nobody got hurt. Thank God they took off, they ran and nothing happened other than my wife getting shook up,"
Brady is not just a congressman, he is also the longtime head of the Democratic City Committee in Philadelphia.
In an election year, one has to wonder if somebody may have been looking for political information, campaign strategy materials or anything of the sort.
Action News has learned that federal authorities will be looking into the robbery attempt to make sure it has not political connection. But police say that appears to have been a random act by criminals looking to break into a nice home.Brady said that's unlikely.
"I don't think so," he said. "They wouldn't come here. If somebody were looking for that, they would be looking at one of my offices, not at my house."
Police Commissioner Charles Ramsey says there does not appear to be some kind of political connection.
"The U.S. Capital police will come out and do a security assessment to make sure there is no connection to any threats or anything like that," said Commissioner Charles Ramsey. "I spoke to the congressman, and he is not aware of any threats or anyone trying to target him." The Congressman and his wife were able to make it to their daughter's graduation party Friday evening. She graduated from Archbishop Carroll. Find out about Breaking News as it happens. Sign up for 6abc.com Breaking News Alerts.
