The guitarist walks out of rehab and his "whereabouts are unknown"…

PETE DOHERTY has left rehab leaving friends “very concerned for his well being”.

The Libertines guitarist has been back in rehab in recent weeks, including a second stint at The Priory in an attempt to beat his addiction to drugs.

However, a spokesperson for the band told NME.COM that Pete has walked for the second time and nobody knows where he is.

He told NME.COM: “Peter left The Priory this morning, his whereabouts are currently unknown although every effort is being made to find him. We are all very concerned for his well being.”

The band are set to make a number of live appearances this week, including slots at the Meltdown festival supporting Morrissey and at the Isle Of Wight festival. It is currently unclear what will happen to the performances.
