How do the police track down suspects so fast?

[LITTLEREDDOT]

The corrosive acid case, the vandalism of the Cenotaph, previous bomb hoaxes. How did the police manage to track down the suspects/culprits so fast? In the case of the corrosive acid, there were CCTV images, but little clues in the Cenotaph and bomb hoaxes cases.

Do you think the police uses the national database of fingerprints? Once the police can find fingerprints (at the Cenotaph, at the phone booth etc), it is a cinch to nail the suspects?

Arrest made in corrosive liquid case

My Paper
Police have arrested a 52-year-old man believed to be responsible for a negligent act on board an MRT train on the North-South Line last Thursday.

The incident that involved an unknown substance - said to be sulphuric acid - left nurse Wan Zahfirah Arshad, 24, with burns on her left buttock after she sat on an MRT seat. She was treated at the Singapore General Hospital and her condition is said to be stable, reported The Straits Times last Saturday.

A police statement yesterday said that the identity of the suspect was established following extensive investigations by officers from the Jurong Police Division.

The suspect's images were recovered from closed-circuit TV footage and he was arrested on Sunday night.

Just use the CCTV, check the time and tally with the ez-link card data when the burger crosses the turn-stile and you got the suspect.
So easy.

For the Cenotaph case, I believe that this was through the suspect's smart phone. Early in the morning when the vandalism occurred there would hardly be anyone at the Cenotaph. As such, the police simply need to check with the telcos on the smart phone signals in that precise (exact) location. Even when a person has left a place hours earlier, the telcos have a record of smart phone signals emitted at that precise location. Trace signals remain in telcos records almost indefinitely.

Why did the burger cross the turn-stile?

So the telcos are an even more potent weapon than finger database for the police.

Yes, Big Brother is watching all the time.

If he did not cross the turn-stile, how he gets on the train?

The Cenotaph incident I do not know of it as I was in Thailand most of the week and never watch the news.

But if it is mobile phone, then as long as it is on, it transmits identifiable info to the base-stations nearby and can track the person.

Always turn off your mobile and take out the battery when you hanky panky.

Do u think that the SPF will explain?

No. But the forum members here will.

Talking about fingerprints....most think that only CID has the database, but hardly anyone knows that there're 2 other databases, one at ICA and the other at NRD.

So why is it so hard to catch the loansharks and bookies ?????????

Ask yourself a simple question: is it "hard" or is it a "lack of resolve" on the part of the authorities to pursue a matter?

So why cannot use phone signals as evidence that Ng Boon Gay and Cecilia Sue, Peter Lim, law professor Tey etc were having rendezvous?

MRT trains got cameras lah.

Never hanky panky unless you can become an invisible man.

In singapore if you want to be a criminal then try your best to use cash in everything. Carry those old phones with an anonymous top up sim card.

 

[laksaboy]

Security cameras, spies etc.

Yes, yes. Also, it would be useful to wrap yourself up like a mummy, as seen in your avatar.

BTW, fingerprints are so passe, so 1960s. These days DNA is the very "in" thing.

i am very curious to know why a person would do such a thing? put acid on a seat and burn someone else who is going to sit on it??? very strange and weird.
