The Chief Minister said the attack was "inhuman, brutal and extremely worrying" and demanded Prime Minister Narendra Modi to take up the safety and security of minorities issue, especially of the law abiding members of the Sikh diaspora, with his counterpart in the UK.
"Their contribution to strengthening race and communal relations in multi-cultural societies is acknowledged and highly lauded by governments as well as political and social leaders in the countries of their adoption. As such, the attack is shocking and totally unacceptable," he said in the statement.
Meanwhile, the Shiromani Akali Dal President Sukhbir Singh Badal has directed the representatives of the party in England to gather all information on the incident and take every appropriate measure to help in bringing the guilty to book.
Badal has also directed his party leaders and workers there to offer "all possible help to the victims and their kin" and work in complete solidarity with them.
