Stop arbitrary detention in Tibet

The total number of known political prisoners in Tibet, according to Tibetan Center for Human Rights and Democracy's database is 988 in 2012. Only small number of them were sentenced, but without procedural guarantees and due legal process, while the fate of most of them remains unknown. An overwhelming number were detained, disappeared and sentenced on obscure charges of ‘leaking state secrets’ and ‘endangering state security’. 

This petition is an emergency call, addressed to Chinese authorities :
"Some 500 monks are facing in this moment arbitrary detention as Chinese governement locked them since the 15th March 2013 in Tonkyab monastery in Tibetan town Golok Gabde for interrogation, intimidation and "re-education". Arbitrary detention concernes even monks that done nothing at all and even if there is no possible charges against them. Telephone and internet lines with all the region of Golok are blocked since the 1st March 2013. Nobody can call to Tonkyab monastery, even in local call. 
This repression is following the arrest of Tritsen, the monk from Tonkyab monastery who wrote the book "Breath of Truth". He was arrested on 11th March 2013, the day after official election of new Chinese governement.
We ask you to stop this arbitrary detention of inocent people in Golok region. 
We hope you will start your reforms towards the state of law by giving the amnesty to all 1000 political prisoners deteined in this moment in Tibet, most of them with no legal charges."

Please, help us to convince Chinese authorities to free people deteined with no charges.
