Lost purse Santandyl market

Hi everyone I would really like your help. 
I lost my purse in Santandyl market last summer.

I had a hard time trying to talk to the police in Santanyl 

Does anyone know how long lost property would stay with the police?
I can’t speak spainish so need a email. Then I can write how to get my purse sent back.
apparently they need me to communicate my wishes.
but I’m at a dead end. Can anyone tell me how to get the police’s email?

Thank you

I am

Looking forward to using the site to learn more about it too .
