Why I don't wear my traditional clothes
He and his compatriots do not dare to don their traditional Bangladeshi tunics.
Some, says S-pass holder M. Jahangir Alam Babu, 42, have even shaved off their beards - normally a symbol of religious piety for Bangladeshi men.
It is because they are afraid of being accused as terrorists, especially in recent weeks.
On the traditional Punjabi suits and the topi cap, Mr Jahangir says: "Yeah, nowadays if you are wearing like this, people can say you are a terrorist.
"It is a bad feeling to be accused. I feel ashamed because (the deeds) of a few others made everyone suffer."
Last month, eight radicalised Bangladeshi workers were detained by the authorities for setting up an Islamic State of Bangladesh cell here.
Five others were deported back to Bangladesh for possessing jihad-related materials or supporting the group's activities.
Late last year, 27 Bangladeshi construction workers were also arrested and deported for having terrorist links and possessing terrorist-related propaganda.
Mr Jahangir believes there is little he can do to change people's perception of his community, but hopes Singapore remains open to hiring them.
Once, he heard his Singaporean colleagues gripe about rumours of his company's new contract for more than 3,000 construction jobs.
They had said these jobs would go to foreigners and would not benefit Singaporeans, he says.
As he heard their comments, Mr Jahangir got worried about the anti-foreigner sentiment.
"Now we scared. What if Singapore (government) don't let Bangladeshi work any more?" asks Mr Jahangir, who moved here in 2008.
His salary of $2,800 a month supports his family - a wife and two daughters - back home.
He claims his pay is less than those of his Singaporean colleagues with equivalent appointments.
Barely two days after news of the recent arrests broke, Mr Jahangir and his Bangladeshi peers were jeered at by migrant workers of other nationalities.
At his workplace, where he is a site engineer, he tells TNPS that many of his colleagues have been making fun of them during meal times.
"Some persons in my company say, 'Wah, now you all Bangladeshi, so many terrorists'," he recalls, adding that the tone used was derisive.
"I feel ashamed. We staying in a nice and peaceful country here. Something like this happen, what they think? That we are not good people."
