BRUSSELS (Reuters) - Two Belgian pensioners, both aged 73, were found guilty of dealing in heroin and other drugs and sentenced to two years in prison this week, a court said on Wednesday.

The elderly couple had taken over the business of their grandson who had himself been imprisoned for selling heroin, cocaine and ecstasy.

The court established that the couple had sold a variety of drugs to people, including one minor, who dropped by their apartment near the northern town of Aalst. Some even came by to make large orders, the court said.

"The only thing that counted for them was to continue the profitable drug dealing business of their grandson," the judges wrote in their ruling on Tuesday.

The couple, who had no prior criminal records, were also ordered to pay fines of 1,000 euros each.
