Last month, law enforcement officials in Spain said they had broken up a major match fixing ring in tennis. The Guardia Civil said 28 players competing at the lower levels of tennis were implicated. It's alleged that a group of Armenians had bribed the players to fix matches. Assignment reveals the inside story of how players and betting gangs are seeking to corrupt the lower tiers of the sport. In many cases, a player only has to lose a set or certain games - not the whole match - to get paid. Players and fixers communicate on social media as matches get underway to ensure the correct outcome is achieved. The rewards can be significant with players sometimes being paid thousands of pounds - often much more than they can earn in prize money. For the betting gangs who have placed money on a guaranteed outcome, the pay off can be much greater. Two years after the BBC first revealed concerns about match fixing in the game, Assignment looks at how the tennis authorities have responded to the issue and examines the measures put forward by an independent panel to reduce the risk of corruption.

Vulcans, Daleks, Martians, Grays - our culture is pervaded by alien beings from distant worlds – some benevolent…most not so much.

Chief astronomer for SETI (the Search for Extraterrestrial Intelligence), Seth Shostak, has devoted his career to searching for signs of alien life. In this programme he tackles the fundamental question about whether we are alone in the universe.

**Some listeners may find parts of this programme upsetting** Emmett Till, fourteen and black, was put on the train from Chicago by his mother Mamie in August 1955. She got his corpse back, mutilated and stinking. Emmett had been beaten, shot and dumped in the Tallahatchie River for supposedly whistling at a white woman. His killers would forever escape justice. What Mamie did next helped galvanise the Civil Rights Movement and make Emmett the sacrificial lamb of the movement.

On college campuses across the United States, students die every year as a result of “hazing” - sometimes violent and dangerous rituals designed to initiate new members into a group to which they pledge loyalty.In 2011, Pam and Robert Champion Sr. lost their son Robert to a hazing incident. Robert was a student at Florida A&M University and a drum major in the college’s prestigious marching band, the Marching 100. He was brutally beaten to death by his fellow band members in an initiation rite known as "Crossing Bus C." Even though this ritual was prohibited, it was widely condoned, accepted, even encouraged, and going through it was considered an essential part of band membership.Today hazing remains rife in all types of groups, from sports teams to all-male fraternities and all-female sororities, the so-called “Greek Letter Organisations” since the names of these social groups are taken from the Greek alphabet.With around 220 deaths attributed to hazing since records began, producer and presenter Nicolas Jackson asks why so many are willing to risk so much in order to become members of a group, and just what can be done to stop it.Producer and presenter: Nicolas Jackson“The Pledge” is an Afonica production for BBC World Service(Image: Family and friends Of Armando Villa call for an end to fraternity "hazing."
