Mexico 'jail break tunnel' opened to reporters
Authorities in Mexico are continuing to search for more than 130 prisoners who escaped from the Piedras Negras prison on Monday.
On Wednesday reporters were allowed inside a 6.5m long tunnel which it was believed the prisoners used to escape before cutting their way through a chain link barrier.
However, on Thursday, a senior official said three recaptured fugitives said they had not used the tunnel, instead walking out of the main gate, allegedly aided by prison guards.
