Read it as: CB and his phone were reunited at 6 km. So if a thief had stolen his phone, the same thief would have to have joined CB at 6km. Whether or not he returned the phone openly.
It is FF who claimed that CB was at a 6km distance based on a ping from his phone. Whereas BKA claims his phone pinged at 5A.
CB cannot use the "someone stole my phone" story without naming the thief.
Is this from a police statement or according to a newspaper?
