Abdullah Senussi is a man from Libya. He was in charge of the intelligence agency of the government that used to rule Libya. He worked for a man named Muammar Gaddafi who was like a president in Libya for a long time.
Abdullah Senussi did some things that were not very nice. He ordered his people to do bad things to the people who did not like the government. This made many people very unhappy and they did not like him very much.
When the government of Libya fell apart, Abdullah Senussi went into hiding. The new government wanted to find him and put him in jail because of the bad things he did. He was on the run for many years, but eventually, he was caught and put on trial for all the bad things he did. The people in charge of the trial found him guilty and he was punished for his actions.
So, even though Abdullah Senussi used to be a man in charge, he did some bad things and was punished for them. It is always important to do the right thing so that we don't get in trouble.
