The man suspected of opening fire on a Boston Police officer on Friday is well know to police. 

Grant Headley, 27 of Dorchester, was released from prison less than a year ago. 

Headley was on probation when he allegedly shot a Boston Police officer. 

His violent criminal record dates back 10 years, starting from when he was 17 years old. 

In 2005, Headley was convicted of possession of a firearm without a license or permit. Less than a year later, he was convicted on another firearms charge in 2006 and sent to jail. 

Headley was out of prison for five months when he got arrested in 2008 for assault and battery with a dangerous weapon. He was convicted and sent to jail on that charge. 

In April 2010, he was arrested on gun and drug charges. He spent nearly five years in prison before being released last April. 

Less than nine months later, Headley is now back in custody, charged with shooting the police officer while he was out on probation. 

Headley lives with his family a few blocks away from the scene. 

His father said he is sorry and is in shock. He said he was a good father to his son and he tried to guide him, but for some reason his son went astray.

"It reflects badly on your family too you know," Grantley Headley, the suspect’s father, said. "It’s not just his life, it’s our life too."

The father apologized to the officer and his family for his son’s actions.

"My family, our sympathy goes out to the officer and his family," he said. "We hope everything works out well for the officer."

Headley is expected to be arraigned on Monday.
