As the victim of a carjacking and armed robbery at gunpoint in Philadelphia, Ravens running back Bernard Pierce had maintained his silence ever since the crime occurred in late June.

Pierce commented on the incident for the first time early Tuesday morning, speaking out via social media.

"One last thing," Pierce wrote on his official Twitter account. "That robbery made me think for a sec that im ashamed of the city im from."

The 23-year-old's 2013 BMW sport-utility vehicle was stolen in the 7500 block of Haverford Ave in Philadelphia.

Pierce, a 2012 third-round draft pick from Temple who rushed for 532 yards as a rookie and was the subject of this Sunday feature in The Baltimore Sun, who was visiting friends and eating pizza when the crime occurred, was unharmed, according to Pierce's agent, Marty Magid.

"Bernard's fine," Magid said in a telephone inteview at the time of the incident. "It's not the best situation, but he's good. It's a shame something like this happens."

No arrests have been made in an ongoing investigation since the car was recovered in another part of the city and processed for evidence, a Philadelphia Police Department spokeswoman told The Sun.

In talking with players and their agents, there's been a common reaction to what happened to Pierce.

While no one assigned blame to Pierce for the situation, it was noted that activity on Twitter and other social media can make players easy targets for potential criminal activity.

If a player announces his whereabouts or plans or has the setting location for his Tweets turned on, that could alert someone intending to rob them. Or it could simply let an opportunistic burglar know that they're not home. In Pierce's case, he doesn't have the location setting switched on his Twitter account.

"Twitter is practically like LoJack for players these days," one agent said. "It's terrible that you have to worry about that, but you need to be really careful how much information you pass on about what you're doing on Twitter. It's a reflection of where we are today in society, but that's the sad reality."
