Priyanka reached Arun Valmiki's home just before midnight on Wednesday and assured all help for Valmiki's family. 

"Arun Valmiki's relatives told me that the entire family was tortured. They claimed that Valmiki was given electric shocks and his hands were crushed under chair by the police. Besides, around 40 members of the Valmiki community were also arrested and  tortured," she told reporters. 

Priyanka was allowed to proceed along with four others after being detained by the cops earlier in Lucknow - for a second time this month. 

Earlier, her car was stopped at the first toll plaza on the Lucknow-Agra Expressway and she was taken into detention. 

"If I am at home, ok. If I go to my office, ok. But the moment I go elsewhere, then they start this tamasha. Why? Eventually I will meet the family. This is becoming ridiculous... people are being affected. Look at the traffic (behind her stopped convoy),"  she said. 

Priyanka also underlined her constitutional right to free movement in the country. 

Meanwhile, AAP MP Sanjay Singh also reached Agra late on Wednesday and met the family of deceased Arun Valmiki. 

He slammed the state government for the anarchy being created by the police and said that the BJP had failed to control the law-and-order situation. 

"First it was the police that murdered Manish Gupta, a businessman, on Gorakhpur and now an innocent man has been tortured to death in custody," he told reporters. 

Arun Valmiki, a sanitation worker, was accused of stealing the money from a building that served as the police station's evidence warehouse, and where he worked as a cleaner. 

He died in police custody. 

A post-mortem was carried out on his body, which has now been handed over to the family.
