'Sabotage' by Anthony Marriott

Steve, Venus and Matt are out on routine patrol in Fireball XL5 when the ship is rocked by an explosion. As the crew desperately fights the blaze, Space City orders LP 22 to assist. Once the fire has been put out, Matt discovers the remains of a remote-controlled neutron bomb; the device has destroyed XL5’s gyroscope, preventing the ship from making a safe landing. Meanwhile, the two Arcon warriors who planted the bomb approach the stricken vessel in their Gamma spaceship- they then use its gamma rays to stun Steve, Venus and Matt and bring them aboard as prisoners…
