Sarposa prison tunneling escape of 2011

The Sarposa Prison tunneling escape was the escape of over 400 Taliban prisoners from Sarposa Prison in Kandahar by tunnel in April 2011.

The tunnel was dug from the outside. As of April 25, 2011, only a handful of prisoners have been recaptured.

Escape
The tunnel used for the escape reportedly took several months to build, was over a hundred meters long, and used sophisticated techniques involving electricity, ventilation, and potentially the assistance of engineers. The tunnel ended in a house outside the prison that had been searched by security forces just two and a half months prior, yet with no suspicious activity reported. However, reports have speculated about whether it would have been possible to conduct the substantial earth-removal required for the construction of the tunnel without security forces having been aware.

Outcome
In the end almost 550 of the prisoners at the facility, managed to escape. Some prisoners were reportedly recaptured, but after the first day the number of detained was 71, only a portion of whom may have been the escapees.

Reports and commentary following the outbreak have focused on the extent that prison officials may have been complicit in the escape, and on whether the escaped prisoners can be expected to join in larger-scale attacks. Political assassinations in the Kandahar area are reportedly down in the last year, but suspicions about government officials, and their inability to protect civilians, has remained high. In response to the escape, the Afghan Uniformed Police established a checkpoint directly across the highway from the prison, directly above the tunnel exit. The security around the prison was also greatly enhanced by coalition and Afghan forces.

Investigation
The head of the team investigating the escape, Mohammed Tahir, further cemented the likelihood that there was complicity from a number of people. He described the tunnel as so carefully planned and sophisticated that it appeared that engineers must have been involved, not merely men with shovels. "The tunnel was dug in a very professional way," said Tahir. "They have used an electrical system and a ventilation system and small shovels and pickaxes for digging and wheelbarrows for removing the soil."
