( CNN ) -- A boy labeled the youngest detainee in Bahrain 's prison system has been released pending trial , one of his lawyers said Tuesday . The boy , Ali Hasan , was arrested on May 14 and accused of participating in an `` illegal gathering '' with about a dozen others , according to the Bahrain International Affairs Authority , the Persian Gulf kingdom 's information office . Authorities accuse him of burning tires at a roadblock . Human rights groups say he is 11 years old . Authorities say he is 12 . Defense attorney Mohsin Al-Alawi said he recently visited Hasan and the boy told him that he did n't take part in an `` illegal gathering . '' The boy sobbed , said he is tired and wanted to go home , Al-Alawi said Monday . Human rights groups had been demanding his release and say he was arrested as the country continues to crack down on anti-government protesters . Another attorney , Shahzalan Khamees , said Tuesday the boy was released Monday without bail or restrictions , on the promise that he would appear to face trial on June 20 . `` Since he was detained , he has one phrase that does not change : ' I want to go home . ' Now he is home with his parents and siblings , '' Khamees said . The lawyer hopes the case will be dismissed , he said . `` He is a child , and under international law children can not be tried . They can make a mistake , but they can not be legally tried for their actions , '' Khamees said . `` The police record states that they saw a bag of garbage in the street and blamed him for using it to block the street , '' he said . Authorities should be `` more than satisfied '' with the time Hasan has spent in jail `` and the damage they have caused to the boy by imprisoning him , '' Khamees said . Bahrain needs to treat children better , he added : `` These are just children . They should be allowed to move like birds from one area to the next without fear of being trapped . '' Authorities said Monday that Hasan was `` receiving social care and tutoring at the ( detention ) center . He completed his last exam of the sixth grade level on Thursday . '' The Bahrain Rehabilitation and Anti-Violence Organization , an Ireland-based rights group , said Monday that there are a `` growing number of children detained for investigation in security cases . '' The Bahrain Center for Human Rights also accused the government of targeting children under age 15 in its crackdown . The rights group said Hasan is the youngest detainee in Bahrain 's prison system . The government did not immediately respond to the allegation . Bahrain has been heavily criticized by rights groups for its crackdown on anti-government protests that began February 14 , 2011 , in the country -- spurred by popular uprisings in Tunisia and Egypt . But the protests failed to gain the traction of other Arab Spring uprisings after a crackdown in February and then again in mid-March of last year by Bahraini authorities -- backed by troops from Saudi Arabia and the United Arab Emirates . Demonstrators and Bahraini authorities have continued to clash , with the opposition accusing the government of being heavy-handed in its crackdown on protests . In November , Bahrain 's Independent Commission of Inquiry issued a report highly critical of the crackdown . The commission , set up by the king , concluded that police had used excessive force and torture during last year 's crackdown . The report recommended reforms to the country 's laws and better training of its security forces . CNN 's Saad Abedine contributed to this report .
Ali Hasan is freed but must return for trial later this month , his lawyer says . Human rights groups say he is 11 , while authorities say he 's 12 . Authorities accuse him of participating in an `` illegal gathering '' and burning tires . Bahrain clamped down on an uprising inspired by the Arab Spring movement last year .
