A los pocos días después

Question

Hi, what does A mean here? Can it be omitted and still be grammatically correct? Thanks a lot,Shirley.

Accepted Answer

Hola Shirley
The text is saying "A los pocos días, sería pasada a disposición judicial..." 
This is a way to say "after a few days...", using "a" followed by a length of time. You can't omit "a".
Other examples could be:

Hice el examen y a las tres horas el profesor me dijo que había suspendido.
I did the exam and 3 hours later the teacher told me I had failed.
Me tomé un paracetamol y a los 10 minutos mi dolor de cabeza había desaparecido.
I took a paracetamol and 10 minutes later my headache had disappeared.

We'll create a lesson with this content.
