These Rutians were members of the Ansata, an underground movement against the Rutian government. They've kidnapped Starfleet Dr. Beverly Crusher from the Rutian plaza following an explosion. Later they transported aboard the USS Enterprise-D, fired at several crewmembers and placed a bomb at the warp core. Chief engineer Geordi La Forge was able to remove the explosive. Following this, the kidnappers transported onto the bridge of the Enterprise-D, shot at Worf, and kidnapped Captain Jean-Luc Picard.
The Rutian boy was a member of a rebel group known as Ansata.
He helped Doctor Beverly Crusher treat Ansata members who were dying from the effects of using a dimensional shifter, which was causing a breakdown in the DNA of anyone who uses it. After Alexana Devos killed Kyril Finn, the leader of the Ansata, who had kidnapped Dr. Crusher, the Rutian boy aimed a phaser rifle at Alexana, but Dr. Crusher told him the killing had to end, and he surrendered. Alexana stated that he was another to take Finn's place, but Commander Riker commented that maybe the end of hostilities could start with the boy putting down his phaser. (TNG: "The High Ground")
These two Rutian police officers served as bodyguards for Alexana Devos in 2366. They accompanied her to the Rutian plaza following a bomb explosion. When an Ansata terrorist appeared they protected her. They were also present when Devos and Commander Riker interrogated Katik Shaw and later beamed into the underground hiding place of the terrorists. (TNG: "The High Ground")
This Rutian policeman told Dr. Crusher to stay back after she attempted to treat the wounded after an explosion was set off by the rebels. He was afraid that another bomb may have been planted by the rebels. (TNG: "The High Ground")
These Rutian police officers were present on the plaza when a bomb exploded and several Rutians were wounded. They also witnessed the abduction of Dr. Beverly Crusher by an Ansata terrorist. Later, they arrested several suspects for interrogations and accompanied Alexana Devos and an away team from the Enterprise-D to the underground hiding place of the Ansata. (TNG: "The High Ground")
These Rutians were members of the Ansata terrorists and suffered from the effects of the transport through a dimensional shift by using the inverters. Dr. Beverly Crusher was kidnapped by the Ansata to treat them but was unable because of the celluar damage caused by the transport device. (TNG: "The High Ground")
These three suspects were detained for questioning after the bombing of a cafe, and the kidnapping of Dr. Crusher by the Ansata, a rebel group. Commander Riker was shocked when he saw the two boys being arrested, and was told by the head of the police that a recent bombing on a shuttle bus was done by a teenage boy. Although probably not members of the rebel group known as the Ansata, they were possibly sympathizers. (TNG: "The High Ground")
These two Rutian civilians were wounded during the bombing of a cafe at the Rutian plaza. Dr. Crusher tried to help them and treated their wounds but was kidnapped by an Ansata terrorist. (TNG: "The High Ground")
