PHILADELPHIA (CBS) — A possible break in the case of a Philadelphia teen killed while riding his bike with a friend earlier this month.

Police have made two arrests in the murder of 16-year-old Saleem West.

Homicide investigators say the two suspects in custody are both 17-years-old.

They are charged in the murder of 16-year-old West, who was a student at Philadelphia Charter High School.

He was gunned down on November 1 in the Strawberry Mansion section of Philadelphia.

Police say on that day he was riding his bike with a friend, who was not injured.

There were 17 shots fired, one of them hitting and killing the 16-year-old.

Authorities say two 17-year-olds in custody have been charged with murder.

Sources tell Eyewitness News that one has made a statement admitting to the killing, but perhaps the most chilling aspect of the story still
unfolding is sources say this murder may be linked to as many as three or possibly four other murders, and additional shootings in the same neighborhood.

Sources say it may all be driven by what may be bad blood between two groups of young men, who live in different neighborhoods just a few blocks apart.

Philadelphia Police are expected to make more details available this afternoon.
