My son is Non Resident Indian living in UK on spouse visa. He was debared from his in-law\'s house before divorce. However, he was not allowed to take his passport, educational certificates, credit cards etc. On enquiry with police, his in-laws said they will not return until the payment of pounds 2000-3000 which in fact he was not given though they claim to have remitted to him thru bank. No evidence regarding this remittance shown to police. However, police says this is a civil matter and hence can not help in recovering the same. Pls advise the remedy now available for recovering the same.
