Italian authorities have arrested a man for being one of the traffickers responsible for a fatal sinking last month, when at least 366 migrants died.
Despite the horrors they have suffered, the 155 survivors are being held in a detention centre on Lampedusa.
More than 500 people were crowded onto a ship travelling from Libya to Italy, which sank near the island of Lampedusa.
Most were migrants from Eritrea and Somalia in east Africa.
One Somali man, Elmi Mouhamud Muhidin, has been charged with a range of crimes. These include kidnapping, rape and human trafficking.
Desperate people from some of the poorest countries in the world had paid more than £2,000 each to be smuggled into Europe.
Many had been raped or beaten on the journey.
Muhidin was captured as one of 90 people on board a boat trying to get to Italy on 25 October.
He was put in a detention centre with survivors from the 3 October sinking tragedy, who said they recognised him and attacked him.
