She spent four-and-a-half hours inside before she was taken away in handcuffs by police.
She covered her head with a coat as she was led from court into a marked police car, which drove her away with a police van escort, its siren blazing.
She kept her head covered, as photographers attempted to take her picture. It is thought she was remanded in custody by the judge after being formally named as a suspect.
She was taken to Malaga police station before being transferred to Alhaurin de la Torre prison while the investigation continues.
The second suspect was driven to court in an unmarked Opel Astra police car.
The Spanish-looking man, in his late 20s or early 30s and wearing smart dark trousers and a pink shirt, was led handcuffed into the building by two uniformed police officers.
One officer was carrying a briefcase believed to belong to the suspect.
In mid-afternoon, security was stepped up as further suspects, including two Irishmen, were brought to court.
Police officers from the elite Special Operations Security Group, wearing all black and armed with machine guns and handguns, were on lookout as three men were led into the building.
A convoy of five police vehicles carrying three suspects raced through the barricades blocking the entrance to the street. The first vehicle was a grey 4x4 carrying the heavily armed specialist security police. Behind it were three marked police vans with their sirens blaring, each carrying a single suspect. Another 4x4 brought up the rear.
Uniformed police marched a middle-aged Irish suspect into the court building in handcuffs. He wore blue jeans and a blue tracksuit top, and was unkempt and unshaven.
A few minutes later officers took in a second handcuffed man, who was balding and middle-aged, also wearing blue jeans and a blue top. A third suspect who arrived in the same convoy was driven away from the area, but was brought back about 20 minutes later and marched into court.
The man, in his early 30s, was wearing a white shirt and dark trousers and was handcuffed.
A policeman at the scene said the first and third men in the group were both Irish.
The three officers from the Special Operations Security Group had their fingers on the triggers of their machine guns as they scanned the area while the three men were led into the building.
Nine further suspects were being held at Malaga, Estepona, Marbella and Fuengirola police stations awaiting their turn to appear in court.
