A Bangladeshi cleaner working in Saudi Arabia was showered with gifts after a photo of him staring into a jewellers' window was ridiculed and went viral on social media.

Nazer al-Islam Abdul Karim, 65, who works in Riyadh, was mocked by an Instagram user who shared the photo, writing: 'This man deserves to only look at rubbish.'

An outpouring of support for the cleaner ensued and Abdullah Al-Qahtani, who has a Twitter account called 'Ensaneyat' - 'humanitarianism' in Arabic - set out to find him.

'This man deserves to only look at rubbish': A photo of a Bangladeshi cleaner staring into a Riyadh jewellery shop went viral on social media after he was mocked online

Al-Qahtani's tweet was shared more than 6,500 times and users were able to identify the cleaner's location from the reflection of the shop window in the photo.

Karim, whose monthly salary in Riyadh is $187 (700 Saudi Riyal), said he didn't realise the photo was taken.

'I was just doing my job as a cleaner in the municipality and found myself in front of the gold shop. I am very happy about the gifts and very thankful,' he told CNN.

'Humanitarian' Twitter account Ensaneyat tweeted a plea for followers to help find the cleaner, who was later identified as 65-year-old Nazer al-Islam Abdul Karim

Al-Qahtani, 38, explained that money is still being sent to Karim as well as bags of rice and honey, return tickets to his home country and two mobile phones - 'an iPhone 7 and a Samsung Galaxy'.

Social media users, particularly Saudis on Twitter, have vowed to continue sending gifts to Karim, including one user who wants to give him $530 (2,000 Riyal).

Once Karim was found, an executive at a Saudi sports channel posted videos on Snapchat showing him choosing a gold set. He also posted photos of the cleaner with his new gifts.

Al-Qahtani told CNN that he was impressed by the efforts made to locate the cleaner and by the kindness and generosity of those who reached out to help him.

The tweet was shared more than 6,500 times and social media users were quickly able to identify the cleaner's location from the reflection of the shop window in the photo
