A war memorial featuring a statue of a Sikh soldier has been vandalised less than a week after it was unveiled.

Lions of the Great War in Smethwick, Birmingham, was commissioned to honour the many from the Indian subcontinent who fought in both the First and Second World Wars.

The 10ft-high bronze statue was unveiled on November 4 - a week before the centenary of the Armistice - but by Friday night had been sprayed with the words "Sepoys no more".

The memorial was commissioned by Sikh temple Guru Nanak Gurdwara Smethwick to mark the sacrifices made by South Asian servicemen of all faiths.

The term "sepoy" refers to Indian soldiers serving in the British or other European armies.

The words "of the Great War" from the statue's title had been sprayed with a black line, while the words "1 jarnoil" had been graffitied on to the memorial.

There was speculation on social media that the phrase could refer to Jarnail Singh Bhindranwale - a controversial figure in Indian history.

He was killed in 1984 in a gun battle with the Indian army after his organisation occupied the famous Golden Temple complex in the city of Amritsar.

West Midlands Police said they are treating the incident as aggravated criminal damage.

The force said CCTV is being recovered and officers are working with worshippers and management at the temple.

Jatinder Singh, President of Guru Nanak Gurdwara Smethwick was extremely disappointed with the actions of the vandals but remained resolute.

"There was some vandalism to the back wall overnight which is very disappointing. The graffiti was cleaned off and the matter was reported to the police.

"Working with the council we won't allow this vandalism to undermine the very strong message created by this new monument and the overwhelmingly positive reaction to its unveiling.

"What makes this incident particularly distressing, is the complete disregard and lack of respect for the significance of the statue and inscriptions, installed recently to commemorate the losses felt by many South Asian families who lost their dear ones during the First World War and mark 100 years since the end of the Great War."

Sergeant Bill Gill, from the Smethwick Neighbourhood Team, said: "We understand that this attack has caused a lot of concern in the community, and we are working to understand the reasons behind it and identify whoever is responsible.

"Officers had already planned to be at the remembrance event which is happening tomorrow at the statue.

"I'd urge anyone with concerns to speak to the officers attending the event."

Anyone with any information is urged to contact West Midlands Police or call Crimestoppers anonymously on 0800 555 111.
