编辑同志: 在一次经营活动中,我因故未能履行合同,对方控告我诈骗,某县公安局以诈骗嫌疑将我拘留。后经亲戚作保证人并交纳保证金一万元,我才被取保候审。后来公安局以不构成诈骗罪,撤消取保候审,可是保证金没有退还,给了我一张罚没清单。请问这种做法合法吗?我可以要回保证金吗? 读者 仇智 Editorial comrades: In a business activity, I failed to fulfill the contract for any reason, the other accused me of fraud, a county Public Security Bureau suspects in my custody of fraud. After relatives as guarantors and pay a deposit of 10,000 yuan, I was released on bail. Later, the Public Security Bureau did not constitute a crime of fraud and canceled the bail, but the deposit was not refunded and gave me a list of fines and penalties. Is this legal? Is it possible for me to return the deposit?
