Jaswinder Singh Multan, a top member of Sikhs for Justice (SFJ), has been arrested in Germany for allegedly being the main conspirator of the December 23 blast in the Ludhiana district court complex which killed one person and injured five others, reports the Tribune quoting sources.

He was arrested after India shared evidence to counter-terror agencies in Berlin.

“We shared all the evidence that we gathered from the blast spot and also how the conspiracy by Multan was hatched,” said one of the sources to Tribune.

On December 23, the explosion took place in a washroom on the second floor of the District and Sessions court complex in Ludhiana at around 12.22 pm.

The counter-terrorism agencies probing the incident had claimed that it was the former Head Constable of Punjab Police, Gagandeep Singh, who planted the bomb at the court complex and died as it suddenly went off killing him on the spot.
